PUPILLARY DISTANCE Measuring Cards 1933 American Optical Co. Set of 3 - $20 - (Fairmont, MN)

Vintage 1931 an '33 Optician's test cards, mounted on black wood blocks. Rectangular one is for measuring pupillary distance. The other two are the same, and for some other type of test (?). They are from the American Optical Co. Southbridge, Mass. Condition on the two square ones is great; the rectangular one has a faint stain. All three to go. From the estate of a local optometrist who practiced from the 1940s and on. I will be listing many optometry items in the next few days from the same estate. Thanks for looking.
