The Leather Pride flag was introduced to the community, to mixed results, by its sole designer - Tony DeBlase - on May 28, 1989, at International Mr. Leather in Chicago Illinois.
This is what Mr. DeBlase had to say on the design itself:
"The flag is composed of nine horizontal stripes of equal width. From the top and from the bottom, the stripes alternate black and royal blue. The central stripe is white. In the upper left quadrant of the flag is a large red heart. I will leave it to the viewer to interpret the colors and symbols."
