In April 1987, the senior assistant postmaster revealed the Postal Service had learned that Americans prefer wildlife stamps to all other subjects. On June 13, 1987, the North American Wildlife sheet became the third US 50-stamp set with 50 different stamps. It was also the third stamp issue with a First Day ceremony outside of the US, in Canada. The colorful 1987 wildlife pane was created to celebrate North America?s variety of wildlife, and animal subjects were chosen to reflect the geographic and biological diversity of creatures native to this continent. And since they are U.S. stamps, all areas of the United States are represented, including Hawaii and Alaska. The USPS selected well-known wildlife artist, Chuck Ripper, to produce the 50 stamp images for this sheet. Ripper had previously created the art for four other stamp issues featuring wildlife. A lifelong wildlife enthusiast, Ripper researched each of the creatures himself, ensuring every state would be represented. Once his list was approved by the Citizens? Stamp Advisory Committee, Ripper created initial sketches based on his own extensive reference library. His sketches were then reviewed by experts at the Smithsonian and National Geographic to check for accuracy. These same experts later reviewed his final artwork as well. To point out the importance of environment and the realism of his designs, he pictured many of the animals with flora common to their habitats.
