Hello,
I have two 90-91 NBA Hoops cards with errors not listed in this site checlist:
#28 Koncak. Koncak appears on back, but Wes Unseld (Bullets coach) appears on front.
#31 Malone. Moses malone appears on back, but Will Perdue (Bulls) appears on front.
I've looked for these cards in the Internet with no success, just another collector doing the same question about #31 Moses Malone card.
Does anybody know about these cards? Are there any other known errors, similar to these ones, in this collection?
Any help would be much appreciated, thanks!
