1989 Pro Set Football Forum

Anyone know why this card have the AFC logo and not the Seahawks helmet in the upper left hand corner like the other prospects?

This is one of the stranger Pro Set cards in their brief history.

In Pro Set's book, published in late 1991, shows every NFL card produced by them up until that point and Jefferson's 1989 card 539 shows it with "scouting photo" printed on front. To date, no copy with "scouting photo" has surfaced.

Numerous collectors (myself included) recall having owned or seen copies of Jefferson's card with the Seahwaks helmet on front, which is the correct format for the subset, as you mentioned. Over the last 20 years, several collectors have emailed me via my blog and forum discussions claiming to own a copy, but, to date, nobody has sent me a photo/scan of one. 

On a similar note of 1989 Pro Set inconsistency, card 529 Brian Washington, shows the words "scouting photo" on front but image shows Brian wearing an NFL uniform (Browns) but to date, no corrections without the phrase have turned up.
