Painted frames and vintage postcards

As part of a little freshen-up of my living room, I gave these wooden picture frames a coat of white paint to brighten them up. 

Then I used them to display these lovely vintage postcards that I think I got from my grandparents many years ago.

I've kept them in the same layout, hanging in pairs with S-hooks, an idea my Mum and I got from an Ikea store back when I first moved into my house.
