This is an old real photographic postcard of H.M.S. Marlborough leaving Valetta harbour, Malta.  I can see no publisher's details.  It has not been postally used.

Condition: A bit rubbed and the lower right corner is stained/ cropped.  Please check the photographs.

UK postage is £1.42.
Postage for the rest of the world is £3.45.  This does not include any customs duty, sales tax, VAT, administration fee etc etc which may be applied in your country (on top of anything eBay has already collected) which you will have to pay.  Postcards will be sent as a "letter" and will not have a customs form attached.  I do not ship to Russia or Belarus.
I will share postage on multiple purchases provided you let me invoice you with the correct amount before paying.  Postage is for economy postage (second class).  Let me know if you want another postage option, such as tracked, and I will invoice you accordingly.  I obtain a certificate of postage for all items I post.
