When I got back into collecting about 6 years ago or so I initially focused my attention on vintage Baseball cards. I put together a 1972 Topps set and various other sets- going as far back as 1887. Heck, I still have a bunch of sets I'm still working on; including some sets I've finally reconciled that I may never complete. I had thought I would be done with collecting modern issues with their shiny gloss and endless parade of inserts that made me want to puke when I initially left the hobby.
Then, one day, I came across a Upper Deck's Sweet Spot autographs on eBay. I was instantly enamored. The idea of putting a piece of leather from a Baseball in a card with a players autographs just seemed brilliant. I had to have one in my hands. That became my reentry into the modern card market. Soon, I was tracking down any Dodger autographed card I could find.
I have several Sweet Spot cards in my collection and promise to eventually show them all here. For know, here is a 2007 Upper Deck Sweet Spot card of Chad Billingsley that has both silver (maybe satin?) stitching and a silver autograph of the pitcher. It is numbered 45 out of 58.
