The bottom image was posted to the Alexander Palace Time Machine Discussion Forum by Carolath Habsburg on 23 June 2011, the others were posted to Foro Diastias by Katyusha on 30 June 2011. The sepia tones were removed, spots in the background were removed, and the background colors were then matched with Photoshop and the set assembled on Illustrator and finally saved as a .jpg file by gogm.
