The latest image of Jesus appearing in an incongruent context appears to be one in a "nacho warming pan" in Florida ... actually, it kind of looks like a garden gnome.

... as long as we're talking simulacra, About.com's News and Issues guide has a lengthy piece on Veronica's Veil, which includes the following:

According to Catholic Online, Veronica kept the veil and discovered its curative properties. It’s said that she cured Emperor Tiberius (of what it doesn’t say) with the veil, then left it in the care of Pope Clement (the fourth Pope) and his successors. Supposedly, it’s been in their hands ever since, kept under lock and key in the Basilica of St. Peter. It is listed among the Basilica’s many treasured relics.

Heinrich Pfeiffer, professor of Christian art history at the Vatican’s Gregorian University, says that the veil in St. Peter’s is only a copy, however. The original, he says, mysteriously disappeared from Rome in 1608 and that the Vatican has been passing off copies as the original to avoid disappointing pilgrims who come to see it at its annual display. It is Pfeiffer who claims to have rediscovered the authentic veil in a Capuchin monastery in the tiny village of Manoppello, Italy.

Not sure how I missed this story before, but it does appear to be all over the web ... Inside the Vatican has a lengthy report ... another source suggests the find was actually made back in 1999, so I guess I'll be forgiven for missing it.
