When I first started making custom hockey cards--way back in early 1997--the first thing I tried to do was make an "Update Set" for the 1989-90 O-Pee-Chee set. The first card I made was of Jeremy Roenick.
I have since tweaked this card, so it looks better now than it did ten years ago (thanks to Dave for your much needed Illustrator assistance).
Here, I used a photo of Roenick from his "emergency call-up" at the beginning of the 1988-89 NHL season. He played 20 games for the 'Hawks, netting nine goals and nine assists, before being returned to the Hull Olympiques of the QMJHL. Notice that he is wearing number 51 and not his familiar number 27. During his first games in the NHL, Roenick wore 51, and later switched to 27 when he became more of a fixture on the team.
I really thought Topps (or O-Pee-Chee) would have made a J.R. card in their 1989-90 set. But I guess they were not as adventurous back then in their player selection. You really had to "earn" getting a rookie card back in the day.
Update: I added the O-Pee-Chee logo to this card on 2/7/2008, because I think it looks better with one.
