The wheels on the far right look more like aftermarket covers over spoked wheels designed to imitate the more expensive pressed steel wheels. And yes, those are hub caps, note that the spare does not have one. The close coupled sedan down the block does have pressed steel wheels, with hub caps as well.

The car in front of the real estate office is a touring car with an aftermarket "all weather" top on it.

I am guessing here, but the large touring car down the block with the twin spares is probably an Oldsmobile Limited, note the large wheels.

The car on the left must be brand new as I do not think the cellulose paints used in that period maintained that level of shine for very long.

I expect most of those cars could jockey out of those spaces, the camera angle makes them look closer than they really are.

Looks to me that the cars are parallel parked on Connecticut Avenue with the old Boss Shepherd mansion at Connecticut and K at the right edge of the photo and L Street at the
left way back behind Stoneleigh Court which fronted on Connecticut. We used to drop off Cousin Alice Averill there after Thanksgiving Dinner in the 1950s.

If you look behind the car on the left you will see, through the glass, a Tin Lizzy.

Regarding these cars parked bumper to bumper. An uncle of mine once told me that in the 1930s he saw a car pull up parallel to a tight space at the curb, a set of 4 wheels on what appeared to be scissor jacks lowered and then moved the car sideways into the spot. I recently saw a demonstration Lexus sedan with a self parking option. It works on a different premise, one that allows it to move back and forth without making contact with either the vehicle in front or behind it. That first system sounded like it was better because it allows you to leave a tight space as well.

Many thanks to Eponymous Roadster for such outstanding information on that car I'd love to drive (although the owner at the time probably cursed it every day). I'm often impressed by the wealth of information provided by ardent fans in a wide array of interests here on Shorpy. Fine minds are attracted to the website that does it best.

On the right there are a few cars parked bumper to bumper such that none can get out. Hope the first car in line has a owner that leaving.

Strange, considering that this was the height of the Model T era. Maybe it was more of a rural thing.

The large, spoke-less wheels seen on the coupe at the far right are actually pressed-steel, disc wheels. The hub cap is in fact the small, screw-on cap in the center of the wheel--what many people might refer to today as a "center cap". In the early days, its primary functions were to retain the wheel and axle bearing grease and to keep dirt and water out.

Despite many car makers in modern times more-accurately calling hub caps "wheel covers", the old term seems to be the one that has survived the generations.

The car in question appears to be a 1922 or '23 Dodge. The high-up headlight position and disc wheels are identifying characteristics of Dodges of that time.

Steel disc wheels were also commonly found on other makes, such as Nash, Oldsmobile, Chevrolet and Studebaker--not to mention Packard--during most of the 1920s. The Budd-Michelin versions used by Dodge and Nash were claimed (at least by Nash) to have the capability of absorbing road shocks and being easier to keep clean, as well as a host of other virtues.

It appears that the smaller, dark-colored sedan parked near one of the trees is also equipped with disc wheels, and possibly so might be the car on the opposite side of the street.

Also worth noting is the small device on the top of the left, rear fender of almost every car in the picture. This was known as a "parking light", and was used to indicate to other drivers (as well as to the police) when an occupied car was stopped at the curb without its engine running. Since the light was very small, it did not have a tendency to drain the battery of a non-running car. These lights had a clear lens in the front and a red one in the rear, and were required by law in some states at the time.

I don't believe those are hubcaps on those big wheels. They are just solid steel stampings.

There is a jaunty little number farther up the block, by the courtyard, with a trunk on the back. It also has solid wheels.

We need better Shorpy auto identifiers for the other info.

There is a shiny car further down the line with modern pressed steel wheels. Per Wikipedia article "Disteel", the Detroit Pressed Steel Company introduced steel wheels in 1917 which were offered as an extra cost option on Duesenberg, Lincoln, Cole, and Page-Detroit vehicles of the 1920s. In March 1923, the Detroit Pressed Steel Company was merged with both the Parish and Bingham Company of Cleveland, Ohio, and the Parish Manufacturing Company of Detroit, to form a new company, called the Midland Steel Products Company. It's not clear to me if the last car has steel wheels or merely wheel covers as suggested by Dutch.

At least in this refined neighborhood, the day of the Model T appears to be over.

I'm sure it's just the photo, however, that last car on the right appears to have bullet holes in the side - a teenage Clyde Barrow practicing his future crime spree? Intriguing are the solid wheel covers, it's the only one on the street with no spokes showing. I'm hoping someone can identify the make or model and tell us about those early large hub caps.

[The "bullet holes" are specks on the photographic emulsion which can also be seen on other parts of the image.]

I wish I could transfer my savings to the DNB since they're paying 3% interest. Much better that the less than 1% I'm getting now.
