THIS PRODUCT IS ONLY AVAILABLE SIGNED BY GREG HILDEBRANDT
In 1981 Greg and Tim Hildebrandt painted 14 pieces of art for a 1982 Atlantis wall calendar. At the same time they licensed the artwork for the Mammoths to Verkerke Poster company in Holland. We just found these in our storage facility rolled up in a tube since 1981.
