Once upon a midnight dreary, I came upon The Instructor: Jointed Toys For Coloring, Cut Out and Construction Work, by Bess Bruce Cleaveland, 1920. In two parts, both of which I now possess, these are 10" x 12.5" books of toy designs by Ms. Cleaveland for use in grade schools by, of course, grade school children.
The originals were published in Normal Instructor, a journal for those educators following the theory and methodology of the Manual Arts system of the turn of the century.
"These jointed toys may be cut with scissors, from heavy construction paper or light card board, or with a jig-saw from thin pieces of wood."
Toys of the 1920's. Wouldn't it be wonderful to be able to use these toy designs today for, oh say, scroll saw projects?
Till next, Gary
