There were two ‘First Day Covers’ issued by the Royal Mail to commemorate anniversaries at Pebble Mill.
The first dates back to September 1972, and celebrates the 50th anniversary of the BBC. Special BBC stamps were produced. The stamp on the first envelope cost only 3p! The logo for this website is inspired from the ‘First Day Cover’ stamp on the envelope.
The second ‘First Day Cover’ marks the 10th birthday of BBC Pebble Mill, and dates from 10th Nov 1981. The price of the stamp has gone up to 14p by this time!
Thanks to Ian Collins from Post Production for making these available.
