- A collection that focuses on two dates: 1862 & 1942. In the former, Lewis W. Leeds' invention of the window envelope is detailed with contracts, bills, correspondence and samples of the envelope. In 1942, his descendant, Morris E. Leeds corresponds with E. Tudor Gross who has become interested in the invention and ends with the article entitled "The Window Envelope," which appeared in the Collector's Club Philatelist in April of that year.
