My love of sketch cards is not just limited to Archer, although that does occupy the vast majority of my attention and wallet. While I search for them every day and have picked up a ton this year I have found a little time to troll eBay for other artwork I could add to my PC.
I love Rick and Morty (Justin Roiland's abhorrent behavior notwithstanding) and have picked up some original art related to the show over the last few years. That has been almost entirely comic books until some eBay splurging yielded a handful of beautiful sketches.
