Autograph Time.
My local Target discounted their stock of 2014 Cryptozoic Adventure Time retail blister packs by 70 percent. Although I'm not a fan of that series, I couldn't pass up on purchasing a blister -- because I had a strong feeling that it contained an autographed card.
The insert odds for the retail packs of this series are as follows: Autograph 1:113; Totally Fabricated 1:500; Sketch 1:3,570.
I purchased one blister pack which contained an exclusive holiday card, and two packs with five cards in each pack for $1.58.

At first I was surprised to see two duplicates in my blister pack, but it turns out there's only 54 cards in the base set.

This foil card is exclusive to this blister pack.
- A11 - Michael Dorn as Gork

Gork can burn whatever it touches, and vomit a fiery substance resembling lava. Voice actor Dorn is best known for his role as the Klingon Worf in the Star Trek franchise.
Update (February 8, 2015): You can purchase this mint card via COMC.com for only $9.99! You won't find a cheaper deal on the Internet as of this writing!
Wow! That blister pack was well worth the $1.50!
