IDW/Transformers blank ?

[synch]

Has IDW done any blanks yet ?.. I want to get a transformers sketch done ... I suppose my next bet would be a marvel blank of some sort ....

New Dimension Comics has done a Transformers variant where the back cover is mostly blank and perfect for getting a sketch on.

 

The only other IDW blank I've seen is a recent TMNT #1 blank produced for the Detroit Fanfare show. I think there are other blank covers but I'm not sure how to get them.
