Three Vintage Hardback Lone Ranger Books from the 1930s and 40s.

These are books 2, 5, and 8 of the popular series of 18 Lone Ranger novels written by Fran Striker from 1936 to 1956. They are in very good condition with no folded corners and little to no damage on the dust covers. I know very little about evaluating vintage books, but these might be first editions for all I know. Each book has the original owner's signature on the inside covers, but there are no other marks anywhere that I can find. These books were reprinted in 1978 by Pinnacle Books, but these three are originals published by Grosset & Dunlap of New York in 1938, 1940, and 1943.
