Inspiration for this collage came from my friends @kwind and @amandal - thank you both for the idea. The first twelve images in my collage are in chronological order - I selected one image from each month in 2015 that made Popular Page, Top Twenty, and/or Flickr Explore. The last four "bonus" images either made PP or TT. 2015 was a very good year photographically.
Beautifully executed.
