1948 Railroad Bangor Aroostook Tamping and similar items

In great antique condition with less than typical used wear... mostly on edges. Some small staining and some light creasing. If pictured item was original folded, then I must ship it folded. 1940s Carbon Blueprint (revised 1948) approved and signed by Chief Engineer W.J. Strout (carbon transfer). Note that this carbon transfer is on normal stock paper but has the typical carbon blue printing color and smudge flaws typical of a real blueprint. I'm not an expert on blueprints but can verify via Maine Transportation that these are indeed real and not reproductions. The last 2 pics are NOT included and are shown for provenance and validity. Its a cover letter related to one of the many blueprints contained in the original folio along with the index. Again those 2 are not included Approx 12.5 x 9" Please note, I have hundreds of different ones... if interested, message me. ***Disclaimer on old/vintage/antique books/paper and the like: Some wear from age, use and storage which may or may not include some, none or all of the following: writing/personalized notes on inside covers and title pages(or notes on pages in the case of songbooks and sheet Music), small tears, creasing, etc.... all typical Vintage and antique book wear. Opposite side may or may not have prints or text which may or may not be related to one shown. Your opinion may differ. See top of description for any outstanding flaws. **All items pictured are fully usable and/or functional unless otherwise noted** Inspect pics closely and ask any questions before buying or offering.
