Tucson's very old inner city neighborhood, The Barrio Viejo, has some of the best murals painted by residents over many years on the exterior of the houses. When my daughter and future husband were in town a number of years back, they took these wonderful photos of one of my favorite houses. I learned recently that new owners of the house built a substantial wall around these murals so they are no longer visible to the public -- and that portions of of it were removed as the owners renovated and up-scaled the house. I am grateful to have these photos of it in which to remember it.
And here's one of the hidden Christ, who appears at the bottom of an adjoining corrugated wall.
