What I see on the sign:
XMAS AFTERNOON DECEMBER 25 '21
3 lines illegible
4th line virtually illegible but seems to have a set of three words followed by a "v" and a second set of three words (the "v" signifying "versus"?)
5th line illegible
VIC HANSON YOUNG COFFY
Assuming that December 25th is a day for recreation, perhaps there was a football or basketball game that day.
One Victor Arthur "Vic" Hanson was born July 30, 1903, died April 10, 1982. He played football and basketball at Syracuse, and I believe he played professional baseball. In the photo with the automobile, it is possible the man standing proudly in the center could be Vic Hanson.
No on-line record of Young Coffy has been found. In the background of the automobile photo there appears to be an oil derrick with a pump arm and linkage to a hidden electric motor. Could this location be somewhere in Pennsylvania?
