Lytham St. Anne’s Holidays are Happy Days LMS

Very rare British railway poster for LMS, circa 1930.
Advertising the resort of Lytham St. Anne’s, Septimus Scott’s bathing scene shows a father and child beside a swimming pool or lido.
The poster is in good condition, on old linen. It has a horizontal fold, some dirt and water staining and a few tiny losses. Could be re-lined or enjoyed as is. I am selling as is, further photos on request.
