A Trio of Advertising Envelopes

Here are a trio of advertising envelopes, starting with one from Bristol in 1913 advertising 'Fitu' corsets.

The envelope below advertised Fardon's Vinegar in 1928 - it was sent as printed matter but charged 2d psotage due as it was liable to the letter rate.  The addressee refused the letter.

Here is an advertising envelope for Radiac Shirts, Collars and Pyjamas.  The firm was taken over and became part of 'Tootal'.
