If you ever get a chance to visit the Sanctuary of Mercy church in Borja, Spain, you're likely to be confronted with a crowd of humanity all gathering around a small fresco on the church's wall. Some 90 years ago, Elías García Martínez painted an image depicting Jesus with a crown of thorns looking forlorn into the light.

It was a pretty unremarkable fresco... until an amateur church volunteer botched the restoration. Thanks, internet.
