@grumpy Looking through 10th Ave in 1940, 364 and 254 would also be small stores, but I can't make that scrawl on the paper a 2 or 3. Looks like a 5.
@grumpy On the 1940s NY Streetview site I can actually find photos on that block for 558-562 and for 568. There is a truck parked in front of 564-566. The other possible blocks have no good photo coverage on that site.
Just a general instance with a catchy name. We're running glitch-soc!
