So I had to check to make sure, but it's been seven years since there were any new cards released of CC Sabathia as a Brewer. (Those would be from 2013's Panini Hometown Heroes.) It makes sense, given CC's success and retirement as a New York Yankee since then. It was brought to my attention recently that he was being featured on some inserts in this year's Archives set. Oftentimes these things have a tendency to burn hot for about two weeks, with lots of examples available on eBay, then fade away once the marks move on to the next new product. Luckily, his cards have been easy to find and priced right.

I agree wholeheartedly that Sabathia's 2008 Brewers run is worthy of a card like this, but why wait until the... 12th anniversary? That being said, I'm glad it exists, and I've been tracking down some of the autographed parallels that have been released. The '76 Traded is a set I've completed, and as far as trades go, Milwaukee hasn't made too many to rival this one.
By the way, you should check out Sabathia's baseball podcast, R2C2, on The Ringer. He's super likeable and apparently enjoys cussing a lot.
