The display commenced with ‘The first new Definitives of the 20th Century’, a study of the Tell, Tell Boy and Helvetia stamps issued between 1907-1933, with examples of their use on covers and postcards. Printed using the typography process by the Federal Mint in Berne, the stamps were produced on granite paper with blue and red fibres. The final issues in 1933 were produced on paper with ‘grilled gum’, a method that prevented the sheets from curling during the printing phase. The presentation concluded with stamps printed for booklets.
The second half was devoted to ‘Switzerland’s Railways & Travelling Post Offices’, with emphasis on the postal cancellations applied to mail carried on the many narrow-gauge private railways.
