Thank you, Ben!
I am not sure the "runes" are readable. At least one of the two layers appears to be written in the Latin alphabet, but it seems very hard to tell characters apart in a black and white picture.
On the other hand, the colour image is quite readable.
About sample size: You are not allowed to view links. Register or Login to view., Anton (who certainly is more knowledgeable than myself) proposed 10,000 characters. When I tried to address the task he proposed, I transcribed You are not allowed to view links. Register or Login to view.: this took me a couple of months, but I worked on both a medieval manuscript and a printed edition, carefully comparing the two sources. Walla should be more manageable.
The painting you posted contains almost 200 characters. If that is indicative of the average text quantity in a single painting, transcribing 50 or 60 paintings could be enough. I don't speak German, but the text superficially looks like "proper" German to me. It seems possible that the statistics of the Walla transcription will not be dramatically different from those of a German text, but we will see...
