Maunsell Street, London SW1

Three fine covers from around the corner of the august Royal Horticultural Society in the quiet backstreets of Westminster. I particularly like the Haywards concentric circles. The floral design is from Burt and Potts of Westminster and the one split into quarters is a Luxfer Prisms, from 16 Hill Street, London EC. Unfortunately, the glass prisms have been replaced by concrete.
