Four Vintage unused greeting cards

Four Vintage unused greeting cards or stationary - looks like these are meant to be folded; the little Miss Pinup Baby one shows it is from 1948; the one with the girl appears still flat but does have a fold mark in the middle showing that someone did once fold that one. The other three are flat and have never been folding to create the card look. The cards would appear to have the fold on the right hand side. Perhaps they were actually meant to be very decorative stationary from back then. Each one measures 6 7/8 inches X 8 1/2 inches.
