The runout etchings are scribed by hand and begin on each side with 3 tiny dots in an upright triangle configuration as in the mathematical proof, the therefore sign ∴. The ® symbol that appears on the Side A etching only, is more of a loosely hand drawn R encircled in a very loosely hand drawn circle.

An alternative press (variant 2) appears to have identical labels to variant 1, but with a darker bolder print used. Plain card sleeve.

The etching ∴ : A DAN 1610 SIDE - A ® 2 : of variant 1 has been altered to ∴ : D DAN 1610 SIDE - A ® 2 : and the A in SIDE - A has been scored through.

The etching ∴ : B DAN - 1610 - B - 1 of variant 1 has been altered to ∴ : C DAN - 1610 - B - 1
