1923 Football "Cards"
 

Hi-
I recently acquired the four cards scanned below and I was wondering if anyone has ever seen these before. They appear to have been issued by The Daily Record in 1923 and they feature high school football players from Dover. The back of each is the same and I have typed it below:
Morristown-Dover
High Schools
Football Game
November 29, 1923
Memorial Field
Morristown, N.J.
For the fullest account of this
game read Friday's issue of
The Daily Record
Morris County's Authority on Sports

Could anyone provide any additional information on these "cards"? Any other examples from this "set"? How about high school player cards from this era, from any area? Were they made frequently? Any help at all is greatly appreciated.
Thanks in advance,
