I'm not sure but I think I've heard this kind of card called a "View-Master" card because it has this circle that you turn to see various images. It was a Make & Take at the Stampin' Up! San Antonio Regional. This card was made with the very cute stamp set Send Me Soaring in the Occasions Mini Catalog. I think we fell in love with this stamp set after making this card!
Here's another image when you turn the circle to see another kite!
