Oh!! It really is paper^ Oh I didnt't touch them. But they did look like thin and delicate crisp paper, not the special plastic paper. MMM made his invitation from that kind of "paper", to wrap around your wrist. It was made by Dupont if I remember well, might be tyvek.
ooh!...I have only seen white paper clothes in the current trend, but I think the colors and finishing techniques used to make the little dresses in the 60s is worth seeing.
