Marx: MXR711B A Four piece rock formation set made from original Marx molds. These rocks were found in various Marx pre-historic, western and WWII playsets from the 1950's through the 1970's.One is about 6 1/2" long and 3" tall and has a cave entrance in it, also includes the rock formation with a body of water (this piece is slightly wobbly but still very usable and other wise in perfect condition) 9" x 7" by 2 1/2" high at it's highest point. The 4 pieces are all perfectly matched in a tan color and were made in hard plastic. Have only a very limited number of sets available. These have never been used before and came out of a large private collection
