Vintage Booklet of Sea Dayak Beauties Nude Post Cards

Published in the 50's, this 8 page booklet contains beautiful, full color postcards of "Sea Dayak Beauties." The ladies are topless and I believe they are from Singapore or the region surrounding it. Each postcard is detachable and has a mini-card that would stay in the booklet, kind of like a receipt. In very good condition and complete, with a few minor creases and corner bends. The cards are postally unused and signed: "Pub. by S.W. Singapore." No reserve~!
