Would that be normal for a body of that age? Also, you may look up Bernadette Soubirous or incorruptibles in general for more photos
Concerning the body of Saint Zita the state of preservation can easily be achieved if care is taken and outside help is in place. The photos do show decay on Zita and this would tend to confirm outside help since it seems unlikely that true incorruptibility would show decay after any stretch of time whatsoever.
Here is a picture of Saint Zita
Saint Bernadette is an obvious reworking since she even looks better than when she first passed away.
This photo shows her after just passing away
This is a recent photo
It seems that there has been work done on the corpse and the maintenance of controlled conditions to prevent further decay again speaks to the absence of incorruptibility in my eyes.
