It's hard to believe that, once one letter went dark, they would let it go until another letter failed. But the most fun signs are the ones in which letters fail, so that they spell something different with missing letters. In 1999, COVE ANT HOUSE was written on a building, from which an N was missing (Covenant House, later the Maritime Hotel).
And the 300-foot-high neon ESSEX HOUSE sign over the signature hotel of the same name got headlines in 1997 when a short circuit darkened the first two letters, leaving a sign reading
SEX
HOUSE
visible to millions of residents living north of Midtown Manhattan.
And I don't even want to describe what "Joe's Cocktails" looked like with the letter T missing.
