The World's Largest Rubber Stamp is a conspicuous landmark near the harbor in downtown Cleveland. Standard Oil of Ohio commissioned artist Claes Oldenburg to create the 28-ft tall, 48-ft long steel office stamp in 1985. Intended for the voluminous lobby of their Euclid Avenue headquarters, the company had a change of management before its completion. The new boss didn't care much for a gigantic rubber stamp with the word "FREE" on it, so it was put in storage.
There it sat for seven years, until another corporate bigwig questioned why Amoco was paying the storage fee on a big rubber stamp. In 1991, Amoco offered to donate it to Cleveland as a grand piece of public art. The city politely refused, noting that they didn't have the funds to install or maintain it. Amoco offered to do the whole job for "FREE" -- and the rest is rubber stamp history.
