I am not certain whether this roller was made for patterning wallpaper, or fabric, or for the printmaking studio, but I guess really it's all the same, and it seems it could be used now for all of the above and more. It looks to me that the roller cover is made of linoleum, mounted on a wooden roller with wire handle. It does require some pressure to get it rolling smoothly, and I have not inked it up to try it, but it certainly seems like one should be able to put it to use. (Though I find just looking it pretty satisfying too.) 

Overall: 7" l x 3 3/8" wide. Roller itself measures 3" w x 1 3/8" in diameter (pattern produced is 3 inches across.)
