Large horses such as Shires and Cleveland Bays were still in use across Cleveland for well over 100 years, into the late 1950s. Robin, Bishop and Duke were the last at Lingdale and feature in this photo as well as the mosaic.
The mosaic was the idea of Lingdale Liftoff, funded by Coast and Country and created by Glynis Johnson and the children of Lingdale Primary in 2013 (according to the tiles around the outside)
Unfortunately the background is slightly damaged at the top left, but hopefully it can be repaired before before spreading to the main subject.
