Mid Century Artist Advertising Poster Tosh Matsumoto Photography Art Vintage

Up for sale is this beautiful poster advertising for Tosh Matsumoto. I'm not sure when this dates but I assume it is fairly early and before he became well known. I cannot find any reference of him working with Arnold Borget.
The poster is a collage of still life images of toothbrushes in various human like, emotional, positions. The work is stunning.
The poster is a thick material and glossy. It measures 14 x 19.5". It's in nice condition but has a nick on the top and signs of fold in the lower corners. There is a small stain on the right margin.
