Picture Postcard / post card
I don't know much about postcards, so I will describe what is on it.
I think this is a 'modernish' card as it has a website on the back - postcardsonline
Front: A picture of a Tropical Island, with palm trees & blue sea - dreamy! lol
It hasn't been used so ideal to send to a friend or loved one - much more personal than an email.
Please see pictures.
