To celebrate the sandwich's 40th anniversary, McDonald’s announced a contest Thursday where it will give away "digital versions of the fan favorite sandwich – almost as saucy as the McRib itself." "With the McRib NFT, you’ll never again have to say goodbye to the sandwich you love," McDonald's said in a statement. To enter the contest, you need to follow @McDonalds on Twitter and retweet the "Sweepstakes Invitation tweet" between Nov. 1 through Nov. 7 from a public account. McDonald's says that by Nov. 12 it'll select "10 fans who will receive the exclusive McRib NFT to add to their personal collection and enjoy even when it’s not on the menu."
