Alexander Calder Tin Can Christmas Tree

Please tell me I haven’t had this sitting on my computer desktop for six-plus months.
Though I can’t tell whether he was actually in or just petitioned to be in the USMC’s camouflage division during WWII, Alexander Calder’s autobiography tells about how in 1942, he was asked by a nurse friend to make small objects and toys for convalescing soldiers in a Staten Island military hospital.
One of those objects: this awesome little, 5-inch Christmas tree made from a tin can.
It sold at Sotheby’s last March for $31,250. [sothebys]
