There are some great pictures of Trentham on this site, as mentioned by VeraH.
William Blake's shots of the Gardens unveil a Trentham I once knew. The pictures of the swimming pool - where else did such a pool exist in England? - reminded me of evening bike treks to it, either along the lake, or, the path that ran adjacent to the Park.
As a Sea Cadet, we'd paddle canoes to the far end of the Lake where the Swiss Chalet sat, dispensing tea and cakes to strollers, or, train riders at the terminus of the little railway.
The Institute pictures truly show the historic past of Trentham. Unfortunately, like Trentham Hall, and the Ballroom, all were demolished.
A picture showing Ash Green Corner with the large brick wall surrounding the Gardens, also shows what was to become Ash Green Post Office managed by the Pavitts. The house sits on the right foreground in the picture.
Believe it was Albert Pavitt as owner/manager, assisted by his brother Harry, who resided a stone's throw off Longton Road above the combination Post Office and store. Besides stamps, you could buy bread and groceries, rent books, and even manage a Post Office savings account.
