M/S of women putting a large pile of letter into a letter box. The commentator informs us of the "... language of stamps" which he describes of the ".. lingo of love".

Each position of the stamp on the envelope has a meaning, e.g. an upside down stamp in the top left hand corner means "I Love You", while an angled stamp in the bottom left hand corner means "I Like You - But Only As a Friend".
Several shots of some famous stamps on display including the Cape of Good Hope Penny and the Hawaiian Two Pence.
