Wishing all a safe #FourthofJuly! In addition to our Red, White & Blue Pinterest board s.si.edu/38sAYST, we’re sharing excerpts from Frederick Douglass’ 1852 speech: "The Meaning of July Fourth for the Negro." (1/8) Douglass, a former enslaved man, was well known as an abolitionist, author, orator, and statesman and served as an advisor to five U.S. presidents, including Lincoln during the Civil War. He has appeared on two U.S. postage stamps, issued in 1967 and 1965. ©USPS (2/8)

The new #USPSTRexStamps depict the lifespan–from baby to fossil–of a T. rex. The remains of the “Nation’s T. rex” inspired the stamp art. A 1st Day of Issue Ceremony streams live at 11AM from the @smithsonian Nat'l Museum of Natural History @NMNH: s.si.edu/30U5vV2 ©USPS @smithsonian @NMNH Discovered by chance in Montana in 1988, the Nation’s T. rex was amazingly & perfectly preserved in action with its jaws around a hapless Triceratops. This so called “death pose” is on view at the National Museum of Natural History @NMNH in its newly opened #DeepTime fossil hall
