I am pleased to present to you this set of Original Antique and Historical Bill Head Receipt Documents / Correspondence. These are beautiful, display well, and would be a fine addition to your collection. We have 2 1913 Invoices dated September 8 and 11, here... These documents have been placed on cardboard that has been wrapped in a clear wrap, such as cellophane, and taped for preservation. My best guess as to when these were wrapped, is probably the 1980's. Keywords: Letterhead, Bill Head, Receipt, Invoice, Document, Correspondence This item was a part of an extensive collection of items mostly from the late 1800's to the 1960's. The previous owner was a highly educated collector of World's Fair Items, Native Americana, Railroad Memorabilia, Ephemera, Dolls, Toys, and Games. She was a world traveler and professional sculptor named Mujana Darian, who has since passed. Most of the information about the collection was lost with her. Considering the quality of the entire collection and the collector, this item is being offered and guaranteed authentic.
