Mine, that is: rusty and/or crushed cans--and this time a lid, to boot! This can, though some earlier ones compete well with it, is my very favorite so far. Am IN love with it: It is such a beauty, I have to look at it every day. It doesn't get put away. Here is the other side of it, along with some other amazing crushed cans in this batch:
(Sorry about the scanner color.) The image above also shows the crushed lid, a more beautiful green than shows up here. The lip of the lid is squashed inward all the way around on the other side. Above-right is a marvelous can that was crushed vertically, and the bottom side is almost still completely round and very attractive. I chose to show the top because its crazy smile does me good.
