Fellow collector, Robert Barbieri was kind enough to pass these pages along to me. The production pages were used for Swamp Thing 5 (1973) “The Last of the Ravenwind Witches”. Based on the coloring style, the acetate production transparencies were most likely used for a trade paperback. I’m unsure which tpb or the year they were created but am really excited to add them to the collection.
Used during the print production process, the two transparent sheets house the text bubbles and final artwork. I photographed the sheets on a white comic backing-board for clarity sake. To see the sheets interacting, view this video.
