This 80¢ stamp from the Pan-American Inverts Sheet is a diamond-shaped stamp patterned after a postal seal created for the 1901 Exposition. The sticker was used to advertise the Expo and to seal envelopes.

The 1901 Pan-American Exposition celebrated the impressive progress America had made in engineering and industry. Six stamps were issued in conjunction with the fair. They were the first stamps of the twentieth century and the first bi-colored general release since the 1869 Pictorials. A printing error caused a number of prized inverted stamps.
