The Northside Independent School District Aquatics Center said the 43-star flag, which would have been correct during the Benjamin Harrison administration in 1890, was a mistake by San Antonio manufacturer, Allied Advertising, KSAT-TV, San Antonio, reported Monday.

"We went on good faith that when you purchase the item that it was the real thing." Allied Advertising, which replaced the flag at no cost, said the flawed flag was created by a designer who is no longer with the company. "Just a simple mistake, that's all," Jesse Castoreno of Allied Advertising said. "We don't have stock art, so it was created," Castoreno said. "Nobody looked at it, apparently."
