The works have come from the estate of dealers Patricia and Robin Pickard, who opened The Church Street Gallery in Saffron Walden in 1983. Bawden had become a friend (he designed a logo for the gallery) and their first exhibition was dedicated to the Great Bardfield artist himself.
The works at Sworders were part of their personal collection and among the highlights is Beechwood, Broomfield, Somerset. The Pickards had bought the 21¼in x 2ft 5in (54 x 74cm) signed watercolour from The Fine Art Society in December 1976.
It is estimated at £3000-5000.
The sale will also feature works by artists such as Cedric Morris (1889-1982), Sir Terry Frost (1915-2003) and Edward Seago (1910-74).
