A Photo from a forgotten era

My Hometown in an age passed long time ago. I've coloured this by the spring fo 2011 after a long work on it.

Based on this site showing the postcard:

The postcard was posted in 1934.06.16, meaning the photo used for it should not be that older as well. So I correct that the photo was from the early 30's maybe late 1920's and not from 1910's.
