We love these dramatic geometric black light posters. They capture so very well a time and place in our lives which seems like yesterday and yet is now fifty years ago. We're so glad certain patterns haven't changed even a little bit. This is one of those op-art pieces which is so vivid and dramatic in black light. We wish there was a way to show it's full impact on line. You'll have to see for yourself. Measures 35" by 23" or it can go vertically just as well.
