Gee, it's not at all deceiving to surround the nodder with Brooklyn Pennants and even to place one in his hand.... How convenient!
The sad thing is that someone a bit less seasoned and more impressionable will probably buy this. I am 99% sure that the hand originally held one of those "Tied Handkerchiefs" on a stick. Hobos like this were big in the '60s, and were portrayed in cheap paintings, bed sheets, underwear, pajamas.... virtually everywhere. This is almost certainly a generic Hobo Nodder, magically transformed into a baseball piece.
