For your consideration is this c1939 “Vacation Cabins” by J.B. Parker floor plan guide. This is a revised version of the original 1932 edition. There are 41 pages. The inside page (probably the blank page) is missing. Other than that, this softcover guide is in really nice condition. It measures 8 1/2″ x 6 1/4″. Page number 38 has an estimated cost of construction. A J.B. Parker guide sold here in January.
