After seeing a number of nice sketches on eBay from this product I grabbed a couple of boxes.

Here are the hits from 2 mini-boxes.






Also included were 2 puzzle cards, 2 line art cards and 4 base.

Ed couldn't have shipped 'em faster -- thanks Ed!

Top right looks like it might be by Jae Lee.

The signers are listed on the back of the cards -- the top one is Jae lee the bottom is Moritat.

The sketches are:
Quinton Baker, Zach Coolsey(?)
???, Dan Gorman
