A pair of covers, the first from 1st January 1840 in the 4d uniform postage period with a Taunton "TOO LATE" handstamp (indicating that the letter missed the post).
The second item is a returned postal packet from 1975 with 11p postage due, with an "UNDELIVERED FOR REASON STATED" cachet with manuscript "Refused". It is likely that the enclosed letter had been sent unfranked.
