A 6 x 4 sepia photograph of Gresley prototype O2 class 2-8-0 locomotive Great Northern Railway number 461 mounted on its original card frame. The bottom frame border is actually signed by Gresley himself and dated by him 'Christmas 1918'. He is in the photograph, complete with obligatory bowler hat, standing next to the loco. Also written by Gresley, the back is annotated '1917 For Haulage of Heavy coal trains, 80 coal wagons and 1300 tons (3 cylinder)' 67 locos were eventually built in various guises, sadly none survived into preservation. A wonderful memento of this fine class of loco
