anything by any of the crew at Firehouse printing (Sperry, Zoltron, Hunter, etc) are some of the highest quality printing you will see. Even if you dont like the art, you can be sure the ink will be layered on so thick it looks painted. And their variants are always highly impressive.
This is the only rock poster that I have from them
The Willy Wonka silkscreen was also one of theirs..........
