White sidewalls both sides. Wonder if the tire tread was multidirectional as opposed to today's tires

Don't know if that day's technology permitted a multi directional tire tread but the tires were manufactured with dual sided whitewalls.

As Shorpy's resident guitar nut, I have to add this to Hayslip's informative post on Duco lacquers.

When Leo Fender began making his solid-body electric guitars in the late 1940s and early '50s, he used Dupont's Duco nitrocellulose and Lucite acrylic lacquers to finish them. The Duco colors, same as used on the cars of that era, included Dakota Red, Daphne Blue, and--my favorite--Seafoam Green. The Lucite colors included Lake Placid Blue, Olympic White, and Shoreline Gold.

So your Pontiac could match your Precision Bass!

GM started using DuPont quick drying Duco lacquer on the Oakland in two shades of blue in the era of this car. Previously car bodies sat around forever waiting to dry to be mated with long completed chassis. According to a DuPont mag I own a GM employee painted a car with this material and was not satisfied with the results; then went at it seriously buffing it to remove the paint. It gleamed! If you decide to colorize this photo make sure it is blue.

According to Zillow:

Built 1908.
7,782 square feet.
Seven bedrooms, six baths.
Last sold in 1998 for $4.9 million.
Current valuation $10.1 million.

This time it's 2120 on Washington Street.

Though by 1925 few men wore silk toppers or women bird-of-paradise millenary, this coupé is ready to accommodate a Ziegfeld girl in full costume if necessary.

Fortunately, many roads were still in such poor condition that the car's high wind resistance would probably not have been the limiting factor as to speed.
