Set of six Ravenhead 'Siesta' glass tumblers, the ubiquitous bark-like textured glasses of the 1970s.
Designed by Hardie Williamson for Universal Glass prior to 1972, the Siesta range was refined and expanded by John Clappison after the Ravenhead Glass re-branding of the Universal Glass Tableware Ltd in 1972 to appeal to a new consumer market.
