The good news? I was offered a true 1/1 Twins card in trade. The bad news: it was a Delmon Young card. The good news, though — we were able to strike up an amicable trade, and I made a new trade partner out of the deal. Special thanks to Topher for pointing The Trumpet Man in my direction.
The 1/1 is a 2009 Topps Platinum, my first true 1/1 besides a few printing plates. The Trumpet Man also did the favor of digging through his other cards, and he came up with about a dozen cards I needed, most being 1990’s cards I hadn’t caught up with yet. Here’s a sampling:
clockwise, from top left: 2009 Topps Platinum #656 Delmon Young [1/1]; 1996 Topps Laser Bright Spots #B10 Marty Cordova; 2004 Fleer Ultra Colby Miller #364; 1995 Upper Deck Electric Diamond #431 Dave Stevens; 1995 Upper Deck SP Championship Series #169 Chuck Knoblauch; 1990 Pacific Legends #17 Rod Carew
I’ve suggested The Trumpet Man reach out to others of the neighborhood of blogging collectors and to consider creating his own blog someday; if you do get an email from him, he has my glowing reference. Thanks again for the trade!
[EDIT: He did it!]
Additionally, here are a few more recent pickups from The Bay and from trades:
clockwise, from top left: 2006 Upper Deck Special F/X Special Endorsements #SE-FL Francisco Liriano (auto); 2005 Donruss Diamond Kings Materials Bronze #129 Jacque Jones [136/200] (jersey&bat); 2005 Leaf Prospects Red #224 Jesse Crain [011/100] (auto); 2006 Upper Deck Ultimate Collection Ultimate Tandem Patches #UT-HK Jason Kubel w/Hermida [24/35] (dual jersey); 2003 Topps Finest #104 J.D.
