This is a very rare poster unavailable anywhere but here on eBay. It features a cutaway illustration of an Atlantic E3a engine with lots of little details on the various parts and functions. It was originally done in color by an artist named Bob Young. The illustrations on his website are stunning.
The printing is top quality - in fact they were printed to show the quality of a Xerox printing press at a recent print show.
This poster is printed on heavy stock and is would look great framed or matted.
The entire sheet measures 12" wide X 18" high.
It will be shipped in a hard tube USPS First Class Mail.
