Santa Fe RR / BALDWIN LOCOMOTIVE BLUEPRINT 3200 - SEEN ONE?

Has anyone seen an original blueprint of a Baldwin Locomotive Works 2-8-2 Mikado steam engine (#3200?) This piece was acquired at an auction awhile back. It measures 2 1/2 feet tall by 11 feet long and is intricately detailed as you might imagine. VERY LITTLE damage has been done to the far right side of the paper by moths (printed on Strathmore). NO DAMAGE done to the actual artwork. Santa Fe logos are in each of the four corners. On the engineers cab, is the name "GEORGE P. MELCHIOR", (spelled Geo. P. Melchior, on the piece). I suspect it is from 1917 or so.... I have pics if anyone would like to see them.

Any input as to value, etc. would be much appreciated. You may e-mail me at: [email protected] for pics.

Thanks,
