100F Block, Middlesex, NY

Here is the 100F Block mentioned on the postcard below. The photo is from a website dedicated to the roads of New York State:

"This is the post office at Middlesex, a hamlet in Yates County at the junction of NY 245 and NY 364. It is also a general store, as is sometimes the case in the small rural towns of Upstate New York. This kind of old storefront, which looks as if it ought to be one of a row of similar structures, is also often found standing alone, looking rather out of place in such a small community."
