This sign is visible on the side of Coopers Chemists in Great Ayton. Its still fairly clear and I read it as :-
Wm Pearson, Builders & Depot for Builders Materials
In the 1901 census there is a William Pearson, 52 Builder Contractor living at Well Cottage. He built the terrace known as Pearson Ville and also the house that became the Worthy Pearsons shop owned by his descendants.
