I don't think I've had an insert or an insert set so intrigue me as this one. I totally missed this release and 2005 was a year I was super busy. But I do remember seeing these in 2008 when I had time and was pretty heavily buying on eBay. I wan't sure what the heck they were, but they were low numbered and it looked like there were a lot of cards to chase.
For those who don't know this insert pays homage to the 1914 Polo Ground game cards and came out of 2005 Donruss Throwback Threads Baseball. A set I'm pretty sure I never opened a pack of. All of the card are pretty similar, they use the same photo on the front and same image and numbering on the back, the only thing that changes is the call and action on the side. From a quick glace over at the Trading Card Database, Robin has over 50 different versions. The most common numbered to just 85 to the most rare at 15 copies.
A really cool insert from a year that saw a ton of inserts, parallel, and variations.
