Pardon me while I have a strange interlude? is a collection of drawings by Andrew Rottner. The quote is from Groucho. No one who has seen it can ever forget Animal Crackers. "Livin' with your folks. Livin' with your folks; the beginning of the end...."
These images were generally stacked and bundled with twine so that only the top image was visible at any one time.

These bundles were shown in several exhibitions in the Bay Area in 2006 and 2007.

This new edition by Super Classy Publishing makes it much easier to see more than one image.
