ERTE poster from 1968, LYRIC OPERA

This is one of those great crazy finds. It was in the back of a stack of frames. I dont think the seller had even looked at them. I asked how much the prints were and he said 30 for any of em. I offered 20 and took it without showing him the image...Erte didnt do many posters so this is a cool find. I found it online for sale for anywhere from 400 to 750! Its in perfect condition and the frame is original. The image is very cool.
