I'm trying to finish up a complete set of 1983 Topps / Topps Traded autographed Chicago White Sox cards. For the life of me, I cannot get Julio Cruz, Jerry Dybzinski or Greg Walker through the mail despite numerous attempts. I even tried bribing Cruz with a loaded Starbucks card. No dice. Maybe I should have sent cash

. Any help with these, and especially Cruz or Dybzinski, would be truly appreciated.
20 Carlton Fisk
393 Carlton Fisk All-Star
23T Julio Cruz
27T Jerry Dybzinksi
124T Greg Walker
(I also need Fisk, but I'm confident that I can get him at a show, so he is less urgent. I might be able to get Walker in person when the Braves play the Padres, but I'm stumped on the other guys.)
Thank you, guys!
