Golovin-Sivtsev Table (Visual Acuity Test / Exam) Pinback Button
Created in 1923 by Soviet ophthalmologists Sergei Golovin and D. A. Sivtsev, the Golovin-Sivtsev table was used for testing visual acuity in the USSR. Recreated on these gifts is the Golovin-Sivtsev table, which consists of two parts. The left part contained Cyrillic letters Ш, Б, М, Н, К, Ы, И in a definite order, with width of each character equal to its height, and the size of a first row character being 70 mm, in the second row it was 35 mm, and 7 mm in the last row. Right part of the table contained Landolt C symbols. No need to be Russian or a medical historian to enjoy this vintage visual acuity test!

It came out exactly like I expected and I love the square, which is different from your typical round buttons! Printing came out just like the photo sample and exactly how I hoped.
