The cards that I got signed were a 1989 Score (what an underrated set) and a 1987 Topps Glossy Rookies. Both cards look good, and I'm glad they came back.
Dunne (b. 1962) played in the majors from 1987 to 1990 and 1992 for the Pirates, Mariners, Padres and White Sox. He had a career record of 25-30 with 205 strike outs and a 4.08 ERA. He finished second in the 1987 NL Rookie of the Year voting (to Benito Santiago).
I mailed to Dunne on June 8 and got the cards back on July 10, for a 32-day TAT.
