Founded by Andrew Ewing in 1904, at its height the company had over 250 shops throughout Scotland. The picture is of a little girl feeding a buttercup to a cow and is taken from a painting by Thomas Curr (1887-1958).
The tiles were part of the Company's distinct branding. Even the floor tiles at the entrance are wonderfully decorative.
The tiles were manufactured by the Glasgow firm of James Duncan Ltd. You can read about them, and their association with the Buttercup Dairy Co here.
