I wonder what is "Miracle" about the ham.
That it was pre-cooked?

You can see 119 on a sign across 47th, and the street crossing appears to be Indiana (better seen on the LOC image), today the view on E 47th looking east toward South Indiana looks like this:

I believe the very shiny car, either new or freshly waxed, parked at the curb facing the camera in the bottom of the frame is a 1939 Nash sedan. The squared-off headlights seemed to be a trend for a couple of car manufacturers that year.

I am struck by how much the scene resembles the area in the movie "The Sting" where Robert Redford's character Johnny Hooker rented a room, right down to the lunch counter on the corner.

The coupe in front of the '37-'38 Buick is a '37 or '38 Chevy and the Mercury on the far left is a 1939, the first year for the marque.

The sign in the lower left has aroused my curiosity - RADIOS INSPECTED FREE.

I was born in 1943 and I have never before seen such a sign.

Why, in 1941, would a radio have a need to become inspected?

Facing us far left is a 1940 Mercury (first year); closer behind the truck is '40 Chevrolet; at the curb on the opposite side is a '39 Ford Tudor behind a '37 or '38 Buick; farther down that side ahead of the coupe at an angle is another '39 Ford.

Always surprises me how often the '38, '39, '40 Fords show up in these pics.

In the novel "Native Son," this corner was the location of Ernie's Kitchen Shack, where Bigger takes Mary and Jan, who want to see an authentic place "where colored people eat".

The book (released in the spring of 1940) revolves around the neighborhood where Russell Lee was photographing in 1941.

If we continue walking towards the L, we will find the shoeshiner we met a while ago on Shorpy.

A Miracle Ham sandwich with Miracle Whip on Wonder Bread and for dessert, Heavenly Hash with Angelfood cake. Of course, if it is on a Friday, the sandwich would be Holy Mackerel. (no meat on Fridays for Catholics in 1941) and don't forget to say Grace before your meal.
