I'm probably going to shoot myself in the foot now, since I some months ago added the signatures manually, but! I have used my day to collect the available signatures on BanknoteMuseum, and convert them into somewhat useable pictures and a spreadsheet.
There were pictures and details of signatures from 1886 up untill the last Markkaa notes. (Meaning P# A50 to P# 123)
Mistakes, spelling mistakes and stuff like that may have sneaked in.
I couldn't remove the background, but at least I could remove the names attached to the BanknoteMuseum's files.
Thanks in advance and hope referee @Hibernia will like to have a look at it :D
