Lot of 77 Vintage Valentine’s Day Cards 1920s-1940s Mechanical 3D Lace 1 Person For Sale

I bought the contents of a trunk at an estate sale. These valentines and many more were in there. Many of these are from the 1920s and 1930s. I am sure a handful from the 1940s. Most (maybe all) are address to Margaret Haefner. Some cards have another name, but I believe that is the giver of the card, when there is only one name. There are many honeycomb 3D, many mechanical with eyes and other parts that move. Many fold out and have lace. Many stand up. The first pic shows all and every other pic is a close up. There are 77 cards in all. There are many cards made in USA and many cards made in Germany. I did not look at makers of all cards.
