Stralsund 10 + 20m (‘interesting’!)

Description

I am selling here my 2 pieces from Stralsund that have been hole-punch cancelled……but then someone has tried to hide that fact and used masking tape to cover the hole cancellation! Its the only time I have ever come across this in regards to notgeld! Both notes are in ‘used but good’ condition- please see scans. Maybe the notes were used again after they had been cancelled!
