Toffee - believe it or not - is a Stoke-on-Trent delicacy. Edward Walker began making his own version in a backroom sometime in the early 1900s... and suddenly 'Walkers Nonsuch Toffee' was a runaway success.
This keystone sits over the original entrance to the Horlestone confectionery factory in Longton.
The factory, just yards from Edward's first shop, was taken over by Walkers in the 1940s as the firm expanded exponentially - and it is still there to this day.
Note the proud Stafford Knot.
