Designs of architectural models to be erected with Richter's "anchor blocks": no. 4 second stage for building with stones of the large caliber (box lid)
Friedrich Ad. Richter was an entrepreneur who purchased the idea of making children's stone building blocks from the Lilienthal brothers and opened a factory to begin producing the blocks in 1880. Richter began selling the blocks with a red squirrel as his trademark label. In 1895, he replaced the squirrel with an anchor. The sets became very popular and were used by both children and adults.
