Is That So, poster. Photograph of Sina in black and white. Did you know that chimpanzees are significantly better than humans on visual memory tests? Researchers found out as late as 2007 that chimpanzees have photographic memory. The poster has a white surface around the collage that highlights the motif. If you choose a frame and mat in the same size as the poster, everything fits perfectly. Frame and mat are not included. Printed on matte uncoated paper.
