NOTE: Sid Eapg (Lethbridge) 2023: This is one of several different patterns given the aka of Hercules Pillar - two from the flint era and one later. This version has a flute between the columns of sunken circles/thumbprints. The pattern named Hercules Pillar by Millard has a raised element between columns of blocky thumbprints. And then there is Hobbs, Brockunier No. 96 which consists of a just a molasses can which has a flute between the columns of horizontal thumbprints.
