In the comments to a post at the Marmot's a reference was made to the links to colonial era photos of Korea that commenter Mika posted here; unfortunately the links are now dead, so I put the photos in a zip file, and they can be downloaded here (The download 'button' is at bottom left, you have to wait 12 seconds).
There are photos of colonial Seoul (Keijo), Incheon (Jinsen), Busan (Fuzan), Gunsan (Gunzan), Daegu (Taikyu), Daejeon (Taiden), Pyongyang (Heijo), Sinuiju (Singisyu), Cheongjin (Seisin), Wonsan (Genzan), Hamheung (Kanko), and Nanan (Ranan). In all, there are about 330 photos in an 80mb zip file. Enjoy!
