Plans to launch a series of Harry Potter-themed stamps in the U.S. have angered die-hard collectors who insist the honour should be reserved for American icons. The U.S. Postal Service is set to release 100 million stamps featuring British stars including Daniel Radcliffe, Emma Watson and Rupert Grint as their characters from the popular film series as part of an initiative to encourage younger citizens to take an interest in philately. However, the plans have outraged collectors, who complain the characters, dreamed up by Scottish author J.K. Rowling, do not deserve a place on U.S. stamps because they are not an American creation. Members of the Citizens' Stamp Advisory Committee, the board which helps the U.S. Postal Service decide on the honours, are also opposed to placing movie stills on the stamps instead of illustrations. Former president of the American Philatelic Society John Hotchner tells the Washington Post, "Harry Potter is not American. It's foreign, and it's so blatantly commercial it's off the charts. The Postal Service knows what will sell, but that's not what stamps ought to be about."
