I have a vintage Book Holder.  It gets mounted on a wall or behind a bench (similar to what you see on the back of pews to hold books).  I believe it is oak under the yellow paint (1 layer of paint).  It measures about 9 7/8" in width x 9 5/8" in height x about 1 3/4" at the base and 2 1/8" at the top.  I'm not sure how old this is but would estimate somewhere between the 1930's - 1950's as I know it was being used in a household in the 1960's.......  It is solid and ready to be stripped or for a new coat of paint as it is a bit shabby as shown in the photo's.
