Here is a small collection of Toaster photos that I have gathered. Much thanks to The Toaster Museaum for providing many of the shots.
The first pop-up Toaster: the Toastmaster 1A1. 
The 4th pop-up Toaster:
the Toastmaster 1A4 (see a pattern?).
Coming soon: photos of the other 4 single slot toasters produced by Toastmaster from 1927-1942.
For more information about the artists, or more Toaster Art, please visit The Toaster Museaum.
Sunbeam's classic T-9 Toaster. Enough said.
One of Toasting's greats: the Toast-o-Lator, model J. The little window let you watch the Toast as it went in one side, and came out the other.
Old toasters that I found as part of the decorations in the Fossil watch store in the Mall of America. *laughs* I really am sick, aren't I?
The Dualit. These Toasters have been around for years, and haven't changed their style one bit. They come in 2, 4, and 6 slice models and in a variety of colours. Rumor has it that this is the Toaster that the Queen of England has in her kitchen!
