The Thermo variant "was produced in a strictly limited edition of only 400 copies" (translated from German), each came with a yellow or red plastic cover and came with a certificate of authenticity:
Loosely translated from the certificate, the comic was an exclusive for Modern Graphics, sold between July 14 and Aug 15 of 1997. The comics were signed by the directors of both Infinity Verlag (Infinity Publishing) and Modern Graphics.
