For this week's theme of water, I have several covers with cancellations/slogans.
Firstly from 1971 a Maritime Mail cancel on an envelope addressed to the Metropolitan Water Board. Perhaps the sender went off to sea and then remembered an unpaid water rates bill. The airmail envelope just adds another unanswerable question to the mystery.
Next a selection of covers/cancels promoting Ports - Port of London, Dover, Manchester and Portsmouth and Southsea.
I'm linking with Sunday Stamps II hosted by Violet Sky at 'See it on a Postcard'. Head on over there for more stamps and mail.
Thanks for visiting.
