I believe the UER in Note 2 on both of these are inerror. ON the first link, the stats are for Edgar, not Tino. Tino played in Williamsport in 1989. He also was drafted in 1988, is 6'2" and 190 lbs according to other cards. The error here is that the photo is of Tino, not Edgar.
The second link, the error is the same, not the name and stats but the photo.
Now the real question is, was the card intended to be Edgar or Tino. In 1990, Edgar was ready to play full time in Seattle (which he did) while Tino was still planned for Triple A in Calgary. He came up to Seattle for 24 games in 1990 butplayed over 100 games in Calgary. I believe the card was meant to be Tino which makes the name and the stats wrong. The only accurate thing is the photo (and last name).
I will entertain trades but please don't offer me a 1993 Dave Stieb for a Nolan Ryan rookie. I prefer player for player (at least similar era and similar stardom).
