My but they were bendy back in 1965. And there is *something* about men in white undies and black knee-socks that just... makes me giggle.
Bridal sets were a staple in the paper doll universe. You get pretty ladies in beautiful dresses, and accompanying men (sometimes with no outfits), and usually an adorable little girl in ruffles. It's win-win-win.
This set is particularly nice- the covers are beautifully drawn, and each of the 6 dolls has a page of clothes (though it's not one of those books with pockets to hold the dolls and clothes). It was published by Whitman in 1965.
