Vintage Mid-century Mechanical & 3d Valentines Day Greeting Cards Lot Of 4 For Sale

This is a lot of 4 mid-century era Valentines day cards, either having a mechanical or 3d feature involved. The first 2 Cards are jumbo sized the Teapot around 8\" long and the Sail Boat around 10\" long. The 3rd card is damaged slightly unfortunately and originally had a 3d feature where the girls skirt would fold open but I only have half of that piece left. The 4th card is a simple mechanical card where you can move the bear side to side like he\'s swaying with his bat. All obviously have writing on them and have been sent but are still really cool pieces of history! Any questions send me a message.
