An unused effect omitted from the original Haunted Mansion (and, theoretically the WDW Mansion), "The Burning Miser" was created by imagineer Marc Davis to be a multi-panel changing portrait that showed an elderly Mansion resident who sold his soul to the Devil....and spontaneously bursting into flames when the Devil comes to to collect.
But...part of the Burning Miser may have made it into the final Mansion....notice the pattern on his chair, and compare it to Granny's rocking chair in the ballroom:
