The flag is a black-white-red horizontal tricolour, with black A and Z flanking the central arms in the white stripe. The arms derive from Elbing: a red cross patty on white above a white cross patty below. The cartouche is black-bordered and white-fimbriated, a fine detail omitted from the FOTW portrayal but present in the printed sources. Earlier initials were somewhat stylised.
Sources disagree over the lower compartment. Klaus-Michael Schneider interprets red overprinted with black hatching as dark red; Stewart and Rehm show black. Rosanoski suggests that the trellis may instead be part of the design, comparing Elblag’s red compartment with a yellow angled trellis. The Zedler pin confirms patty crosses and has a black trellis on red, corresponding to the Esso version, though its lines are angled rather than Esso’s vertical-horizontal grid. Small printed crosses can look fourché, with straight sides and V-shaped ends, rather than true patty crosses.
