Glad Houser cut many puzzles and ran a lending library in the Litchfield, ME area in the 1930s. Her puzzles are extremely well cut with a very intricate interlocking style and much color line cutting. This was one of her lending library puzzles and had one replacement piece when we acquired it, which I have retained (despite its shortcomings) because it probably was made by Houser herself. The bane of all lending libraries was the frequent disappearance of puzzle pieces leaving many of their puzzles incomplete. All sorts of fines and restrictions were tried by the library operators, but to little avail, and with declining interest in puzzles after the initial fad of the early 1930s, most were closed by the late 30s. The American puzzle maker Glad Houser is not the artist Tsanya. Tsanya prints never had American copyrights. All Glad Houser ever did was past 1920 Tsanya prints to wood and make puzzles out of them, simple as that. Glad Houser was never an artist. She was an educator.and Libarian
