60's "How to Draw Trees", "Color in Trees, Shrubs, Weeds" Art Instruction Books

This is a pair of Walter T Foster "How To Draw" books. "How to Draw Trees" and "Color in Trees, Shrubs, Weeds" are both written by Frederick J. Garner. They are large size, softcover books. I believe they are from the 60's. In excellent vintage shape, there are no noteworthy flaws.
