Copy of a blueprint with 'NYCRR (Northern District), Signal Dept., Detroit Mich., Dutton, Ont. East, Cut Section, Automatic Signal Circuits, May 1, 1963' as the title, in black. It is the 1st revision of this blueprint. It is signed by 'E.J. Seyfold'. The blueprint displays electrical diagrams and a track map. It is four-hole punched and was 'Printed in U.S.A.'
The item is in fair condition. It is dirtied and somewhat faded, the top corners are folded, and there are rips along the bottom edge. It has been folded, so there are two vertical creases across the page.
