Hi all,

I recently obtained a set of 1968 KDKA Steelers cards, and I added them to my vintage football card gallery. I am looking for information on one person, the trainer on this card:



Does anyone know Mr. Berlin's first name? I'd also like to add his college and hometown, as I've done for the other coaches and players.

Also, does anyone know why Ray Mansfield's number changed between 1968 and 1970? Just curious. Below are his KDKA card and his 1970 Topps card.
