After they signed the intermediate-range nuclear weapons treaty in December, it was widely predicted that President Reagan and Soviet leader Mikhail Gorbachev would be nominated jointly for the 1988 Nobel Peace Prize. And so they were, a committee source said yesterday.

The source, who asked to remain anonymous, said other nominees for the prestigious prize are Philippine President Corazon Aquino, Pope John Paul II, Indian Prime Minister Rajiv Gandhi and jailed South African nationalist Nelson Mandela.

Someone, seriously or not, also nominated Austrian President Kurt Waldheim, currently under investigation for alleged pro-Nazi activities during World War II.

Jakob Sverdrup, director of the Nobel Institute in Oslo, refused to confirm or deny any of the nominations, but said that 70 individuals and 19 organizations have been put forth for the 1988 prize. The deadline was Feb. 1, but letters postmarked by that date were still arriving, the source said.

The Nobel prizes will be announced in October.

Michael Jackson's Italian Mob

About 100 Michael Jackson fans mobbed a bank in Rome yesterday after a radio station incorrectly announced that tickets for the singer's tour would go on sale that day -- five days before their actual sale date.

The bank, which is handling ticket sales for Jackson's concerts, nevertheless decided to oblige the crowd by taking their orders. The singer will open his European tour with concerts at Rome's 50,000-seat Flaminio Stadium on May 23 and 24 and will perform on May 29 in the 45,000-seat soccer stadium in the northern city of Turin.

The Vanna White Fur Flap

The Washington-based animal rights group People for Ethical Treatment of Animals sent a strong message to author/letter-turner Vanna White when PETA member Tom Meinhardt destroyed a red fox coat in front of a Cincinnati hotel where "Wheel of Fortune" was interviewing potential contestants.

Carrying a banner that read "Vanna, the animals are dying to see you in fur," a PETA spokeswoman said Thursday the message to White is: "You're very beautiful and you would look attractive no matter what you wear, so you don't have to wrap dead animal bodies around you."

The group says that fur coats are glamorized when White, hostess of the popular television program, models them.

The Occidental's 1924 Repast

And for nostalgia fans, the Occidental restaurant will take a step back in time tomorrow night when it invites Washingtonians to toast its 1924 menu -- complete with 1924 prices. Celebrating the first anniversary of its reopening, the restaurant will boast roast prime rib of beef for 80 cents, broiled half chicken for $1 and sea trout meunie`re for 75 cents. But liquor and wine remain at 1988 prices, the menu announces.

American Express, Exclusively

American Express' slogan is "Membership has its privileges," and holders of the credit card who happen to be fans of Frank Sinatra, Dean Martin and Sammy Davis Jr. may agree. The Rat Packers are booked at the Capital Centre March 31, and American Express reports that it has reserved "a significant portion of the house for all shows in each city, and will make them available to card members in advance of sale to the general public."
