He posted a black and white photo of himself on his Facebook page with the caption: "Throwback Thursday -- I was doing selfies 60 years before you Facebook folks. Eat your heart out Ellen!"
The Ellen reference is, of course, to Ellen DeGeneres, who took a selfie with movie stars at the Oscars that went viral and holds the record for most retweets. He tagged the page for "The Ellen DeGeneres Show" in his update.
Powell's selfie is also going viral, with more than 65,000 likes as of Thursday afternoon. But it doesn't beat Ellen's selfie, which has more than 3 million retweets.
Love Throwback Thursday (especially when it involves selfies)? Me too. Follow me on Twitter: @lauraelizdavis
