You're going to have to click to enlarge this picture to appreciate the details here. Bernhard Altmann layers two cashmere sweaters. The deep golden yellow cardigan has polka-dot cut-outs. It is worn over another short sleeved sweater that is half black, half white. Wow. Just wow. Set sold for $150 in 1956 (about $1206 in today's dollar.)
