Dancing in the Yard

A Vintage Photos Theme Park photo for the theme of gotta dance!—dancing of any type.

This is an unused real photo postcard showing a couple dancing outside in the yard with an accordionist providing the music and another fellow watching the proceedings (see the full version of the card, which simply has white space on either side of the image).

A number of houses and a water tower are visible in the distance beyond the fence, but there's no name on the tower or any other clues to identify the town.

Finally, am I reading too much into things, or could the female dancer actually be a man dressed as a woman? If so, is it possible that the other dancer is a woman dressed as a man?
