davidcyclebackI think someone sneezed on the R.
It may be a legitimate printing miscue. In the Shappe variations, it's a fair guess that something got stuck on the lower part of the 'R,' which could theoritically produce staining on some cards. If some dishonest person was trying to disolve the bottom of the R, that wouldn't explain why there was staining on the rest of the R. You'd want to rest of the R to stay put.
Solvents that disolve lithographic ink smell strong, like alcohol and paint thinner.
Most would not pay 'Shappe' money for the card due to the stains.
