Did you click on the buttons? So you know that BIG NUMBER WORKSHOP was proposed by Spatiotempora. Please visit its website to learn more.

The woodcut image of a big number workshop has been appropriated from "Ain new geordnet Rechenbüchlein auf den linien mit Rechenpfenningen" by Jacob Köbel, 1516.

Rechenpfenningen or reckoning pennies were counters, also knows as jettons. They were factory-made like coins, but had no monetary value. The whole this business was called counter castings.
