A unique "Dream Date" Barbie and GI Joe combo will auction at Nate D Sanders with a minimum bid of $3,500.
The prototype was made by GI Joe creator Donald Levine for a pitch, but was never produced as Hasbro was unable to convince Mattel to let it use the Barbie brand.
The box reads: "The Story / It's June week at the United States Naval Academy at Annapolis. Midshipman, GI Joe, has asked the most beautiful girl in America to the Cotillion Ball. Barbie is dressed in a mid-1960's prom dress.
"GI Joe is dressed in his full-dress service academy uniform. Before the dance is over, will he and Barbie take a stroll in the moonlight along Flirtation Walk?"
You'll have to buy it yourself to find out. The auction ends on October 30.
