Reference Covers in 1970

It has always been my intention to make this website a visual resource for collectors of British first day covers. If you think that you have any BRITISH first day covers not on the website (NOT souvenir covers*), and would like these featured, please email me in the first instance at [email protected] giving brief details of what you have. I am looking for different envelope designs to the ones currently on my website. I cannot always promise, but I will do my best to answer you within a couple of days.
