The first stamps in the series issued by the US (#2426 and #C121) were issued on October 12, 1989. The USPS had planned a first-day ceremony to be held in San Juan, Puerto Rico, but the island had been devastated by Hurricane Hugo weeks before and the ceremony was canceled. However, stamps were still sold and covers canceled there on that day. The two US issues were a 25¢ stamp picturing a ceremonial wooden statuette from the Mimbres culture of the American Southwest and a 45¢ airmail picturing the Key Marco Cat, a wooden figure made by the Calusa Indian tribe of southern Florida.
