Very rare poster from the April 1-29, 1973 Washington National Gallery of Art exhibit of Impressionist and Post-Impressionist Paintings from the USSR (Russia).  The poster depicts a Matisse painting.  The size is 23 x 36 inches.  It is unframed.  The colors are still vibrant.  The poster does have some condition issues.  At the top there are two damaged spots with small holes.  These are visible on the front and back (see pictures).  I believe these were caused by someone pinning the poster up sometime in the past.  Also, there is some foxing on the bottom section of the poster.  Overall, the poster is in good condition.  Other than the noted damage, I do not see any creases or tears.  The poster will be shipped rolled in a container for protection.
