Wotton Auction Rooms in Wotton-under-Edge, Gloucestershire, will sell the artworks this week, after the collection was unearthed in the Cotswolds. 

The auction house’s managing director, Joseph Trinder said the paintings, which date from the 1920s to the early 1990s, “were essentially works of propaganda”.

The artworks are being auctioned as separate lots with estimates starting at hundreds of pounds depending on size, BBC News reports.
