1960s vintage framed botanical prints, wild mushrooms - West Germany

Set of three vintage wild mushrooms or toadstool prints, dated 1961 and 1962, marked West Germany. These are in matched natural birch finish Ikea style frames. (I'm not sure in these are actually real wood or not under the birch laminate?) The frames measure 9 1/2" x 11 1/2" overall, and all of the prints and the picture frames are in very nice condition.
