This robot is singing a song of love! A perfect Valentine's Day (or any day) greeting for your sweetie or your favorite music buddies. This is a set of 6 postcards. FREE SHIPPING! (Only shipping within the USA at this time.) Postcards are 5.5x4.25" with a smooth matte finish on 15pt stock. The design was a collaboration between me & artificial intelligence!
