The inside cover of the 1950 Block Shop Catalog reveals that the toy store was located at 58 Wall Street in New Haven, Connecticut and that their telephone number was 5-9919. (I remember the prefixes being Spruce and Main but this phone number has the third number as 5 - which is JKL - so I'm not sure what the prefix was). The inside cover bears Ruth Fallgatter's signature and indicates that it is the catalog for 1950.
