A lot of people hate the 1991 Fleer set. I liked it when it came out, and I still like it today. It is easy to spot in a box, and it is easily recognized. The card stock is also nice, a bit above par of some of the other early 90s stuff. The cards look sharp when signed, and really nice when scanned.
I mailed to Canseco on July 15 and got the cards back on October 9, for an 86-day TAT. I paid a fee of $5.00.
