I have an original blueprint poster from the Gray Motor Corp in Detroit, dated September 1, 1922, that lists the Department Heads and Overhead Accounts for the company. Since Gray began in 1922, this may be the first listing for this staff, and appears that it was intended to be hung on the wall. It measures 14" x 17" and is in surprisingly good condition. The reverse has age marks and foxing but no rips or tears. It doesn't seem like there are many Gray Motors enthusiasts around and I have been checking reference sites. I'd like to give this to a Gray Motor Club, museum, or collector but unsure where to begin. Thanks in advance for any help.
