This is an Alice card I purchased at an imported goods store. It's smaller than a typical postcard. Approximately 8 x 15 centimeters. The retro color scheme is stylish. I think there are various uses for it, such as a short note or an add-on card for an envelope. There is yellowing on the edge of the back side (it's unclear whether this is due to aging or a design to give a retro feel). Please check the photos.
