I don't remember where I got this but it was definitely on a fleamarket somewhere (like all of my postcards).
I think it's such a pretty, yet kind of strange, picture. It looks almost like a painting but I believe it's a photo that's been colourized. The blurriness and colours sort of blend together in a mish mash and it really reminds me of how summer in Sweden is like. A million blends of green.
Don't you just want to sit on the bench under that tree and soak it all in? I sure do.
