Primus is one of the rarest and most desirable of all the Lehmann toys. They were expensive toys, and few were made. They were made from 1913-41 and were called EPL 670. He is a roller skater that stands on two legs and rolls forward by moving the legs as shown. He is 9 inches tall with spectacular lithoed features in near mint condition. Surely this is one of the finest in the world.
