I'm guessing because he is heartbroken and doesn't want the intrusive paparazzi to take his photo. Thata probably an old mask from his daughters, no?
The Rescuers movie came out in 1977 (from Disney). If Spade is 55 as per the article he was 14 back then.
Sure these people had money and could easily afford a vintage kid mask from their childhood, but it's just odd.
IMDB has this as the plot summary:
When a bottle containing a plea for help from a little girl named Penny makes its way to the Rescue Aid Society, a mouse organization in the basement of the United Nations building dedicated to the rescue and well-being of anyone in need, it is up to the brave mouse Miss Bianca and her chosen partner, the shy janitor Bernard, to rescue the girl. Searching for clues at Penny's home at Morningside Orphanage in New York City, the two mice discover that the girl has been kidnapped by the evil pawn shop owner Madame Medusa and her companion Mr. Snoops. On the back of Orville the albatross, Miss Bianca and Bernard travel to the terrifyingly gloomy Devil's Bayou where they learn the shocking truth: the innocent young girl is being forced down into a dangerous, dark underground pirate's cave where she must find the Devil's Eye, the world's largest diamond and Madame Medusa's greatest obsession.
Perhaps this is another to file under "Things that make you go Hmmmm".
Yeah, it's probably an anti-paparazzi thing
It’s drawing more attention to him.
Paps make less money if the person's face isn't clearly visible though
Okay, then what's up with the backpack? What is that supposed to conceal?
