Only 1 of those is a demo (Pipe Smokin' Brick) and the artwork (both small and large/high quality -- scanned by myself) for the demo tapes are in the .zip files on this site where you download the tape. The smaller artwork is also at my other website: http://fireska.sitesled.com/ash.html
The Sessions 7" doesn't have artwork... it is just a black vinyl in a sleeve that came inside early copies of the Trailer 12" EP.
