I picked up a nice item today for my advanced Johnny Vander Meer collection.
Here is a game used 1938 NL (Ford Frick) ball that was pitched by Vander Meer and fouled into the stands at Cincinnati Reds' Crosley Field. The patron inscribed the ball, but did not note the actual game day. The ball had been stored in a closet away from light for virtually the entire time since 1938.
BTW, the central focus of my Vander Meer collection is the year 1938, so this is a pickup that's obviously right in my wheelhouse.
Many thanks to History of the Baseball and net54's own, Brandon G. for confirming that the NL Frick ball was correct for the year in the inscription.
