GREAT BRITAIN 1965 COMMONWEALTH ARTS FESTIVAL PROOF SINGLE, DELACRYL
6d Commonwealth Arts Festival imperforate proof single, with notably different design to issued stamps, printed using De La Rue's Delacryl process to showcase the technology and tender for printing contracts. Extremely scarce. Fresh and fine. Mint lightly hinged. SG670var; SC429var
Note: touted as a superior printing process, Delacryl was in fact an enhanced offset-lithographic technology. Despite considerable marketing effort, just two issues were printed for Great Britain using the process – the 1969 Post Office Technology and 1970 Commonwealth Games commemorative sets
