In silver-plated steel and "cold" enamel, 39.9 x 30.8 mm, weighs 2.1 g. Stamped out of a very thin, almost foil-like sheet of steel, this piece has a "tinny" quality characteristic of some of the earliest Soviet propaganda and labor award pins and jettons. The artwork shows a strong influence of the Constructivist style popular in the 1920s but largely phased-out by the end of the 1930's decade. The inscription on the red scroll is "Shock-Worker"; the numeral "4" signifies the goal of completing the assignments of the Five-Year Plan within four years. The raised inscription along the edge of the cogwheel is "For the Socialist Competition."

In very fine to excellent condition, uncommonly well-preserved for a badge of the First Five-Year Plan period. The brittle "cold" enamel is largely intact, having only some very minor chips along the edges of the scroll. The raised artwork shows practically no wear. The fragile silver finish is still present and bright in the recessed areas, while the background steel shows none of the usual pitting or heavy oxidation. The screw post is full length, over 9 mm. The screw nut is a replacement, but it fits the screw perfectly.
