Vintage plastic alphabet and number stencil. Was a free gift in Practical Householder magazine, so it probably dates from the 1950's or the early 1960's. I have not tried to wash off the ink marks left as I think it adds to it's charm! Also has a ruler along the side (in inches). The plastic is soft and bendy.
Good vintage condition.
Measures approx. 8" x 4 and 1/4". The individual letters and number measure just under an inch high.
