This appears to be a record of the registration of the very familiar, classic, Zeus logo as a trademark. The trademark appears to have originally been applied for in 1966. The holder of the trademark since 1990 appears to be Iberciclo SA. Iberciclo SA appears to be a company, based in the Basque region, that no longer exists.
