Those are two pictures that I took atÂ Old City Hall in Richmond, Virginia, USA.
But the picture wont fit in the proportion for my wallpaper so I put the twoÂ togetherÂ using Gimp making the necessaryÂ adjustments to fit everythingÂ togetherÂ in a 1920:1080 ratio picture.
We can say there is is one tree representing each season: the green at left as Summer, the white cherry blossom as Spring, the one without leaves as Winter and the last with brown leaves as Autumn. Unfortunately the sidewalk and triangles lose the original effect but the pole in the middle created an interesting one.
The high resolution picture is available in my Flickr. I used a Canon Powershot G10.
