On Friday the 13th of January 1950, Dad was sketching jazzmen at the Central Plaza in NYC. This is his Pee Wee Russell.
He did another caricature in the same style, but didn't get it signed. Who it is is a mystery.
The post card advertising the event listed these other musicians:
Wingy Manone • photo here
Pee Wee Russell
James P. Johnson
& the guest of honor
Quite a collection. But a Google Images search across the field turned up no hot leads. Without the other illustration in front of me, Wingy Manone seems a possibility.
That post card, by the way, has Dad's address as 422 E 11TH ST APT 14.
422. Nothing about 5/8.
