Burger King announced that it worked with four other fast food chains to create a "Peace Day burger”after being rejected by McDonald's, reports USA Today.

The special-edition sandwich features elements from Burger King’s Whopper, Denny's Bacon Slamburger, Wayback's Wayback Classic, Krystal's cheese Krystal, and Giraffas' Brutus. The chains will hand out 1,500 burgers at a pop-up restaurant in Atlanta Monday, Sept. 21.

The burger will raise awareness for United Nations’ International Day of Peace, which coincides with the opening session of the United Nations General Assembly. On that day, the U.N. encourages ceasefires in all combat zones and promotes educational programs on issues related to world peace.

Last month, Burger King pitched McDonald’s a burger mashup via full page ads in the Chicago Tribune and New York Times. The proposition was a call to "cease fire" in the burger war between the two fast food giants and to create a Big Mac-Whopper hybrid. Burger King said profits from the burger could be used to support the non-profit, Peace One Day, which helps promote International Day of Peace.
