Usually the Bat signal is spotted in a dark sky over Gotham City. But in one Illinois home listed for $2.55 million, the symbol is found under water on the bottom of the pool.
Although spotting the signal in a pool is pretty uncommon, the story of how it got there is not that strange.
According to listing agent Beau Carstensen, the owners' son loved Batman growing up, and they decided to surprise him at age 3 or 4 with the graphic at the bottom of the pool.
"A guy came out and freehand drew it, and they [the owners] just kept it over the years," explained Carstensen. "One of the son's friends posted it on YouTube later, and that's when it went viral."
The Bat symbol is only one of the interesting characteristics of the Hinsdale property, adds Carstensen.
"The intrigue more is with the property itself," she said. "It's one of the few large parcels in town on 1.67 acres, and the classic architecture of the home has a lot of unique features."
Built in the late 1920s, the house is a classic Tudor, measuring 3,754 square feet with 4 bedrooms and 4.5 baths. Located at 510 Woodland Ave, Hinsdale IL 60521, the home also includes a 4-car garage, hot tub and tennis court.
According to Zillow's mortgage calculator, a monthly payment on the home would be $9,095, assuming a 20 percent down payment on a 30-year mortgage.
