9/10/18 - This is an original GECO factory 50 year commemorative book. The factory came out with this book in 1937 (and the book is dated 1937 on the last page) to commemorate sales and production / product lines over the past 50 years. The book is softcover but in tact and completely original. The pages are all in tact and have some light wear. There's wrinkling / damage on the cover, but this is not excessive. See photos. Guaranteed original and scarce!
