Pope John Paul II, meanwhile, continues to sell.

"We think people are very fond of the old pope, and we're waiting to get to know this one," said Letizia Falasco at Creazioni Falasco, which makes everything from religious medals to key chains.

"I think people are still a little skeptical because they don't know him."

Some souvenir shop owners around the Vatican said they expected to get some Benedict items by tomorrow, in time for his formal installation as pope. But they said they had not heard from suppliers and had not tried to reach them to find out whether they would come in time.

Shops displayed the new pope's books prominently in their windows — but the photos, medals, key rings and post cards inside still showed his predecessor, John Paul.

A few people came in asking whether Souvenirs Traspontina was selling images of the new pope, clerk Carlo Bernardi said.

"I told them that, no, we weren't clairvoyant," Bernardi said.

Estimates on religious memorabilia sales are hard to come by, but by most accounts it is a small market. Falasco said her company has sales of $2 million a year, of which 5 percent only comes from papal items. Creazioni Falasco probably represents 2 percent to 3 percent of the Italian market for religious items, she said. Other companies would not cite sales figures.

Experts say Benedict may be more of a marketing challenge than his predecessor, whose broad appeal translated into a princely demand for pictures and keepsakes with his likeness.

"It's a matter of whether the new pope is going to reach out as much and connect to the various constituencies around the world as much as the previous pope," said Roland Rust, chairman of the University of Maryland's marketing department.

"He's a powerful symbol no matter what, but connecting as a personality creates another dimension."

But it could just be a matter of time before demand picks up for items with Benedict's likeness, said Richard Pomazal, a professor of marketing at Wheeling Jesuit University in West Virginia.

"Obviously, the former pope was around for 25 years," Pomazal said. "Pope Benedict is new and apparently not the 'in' thing."

John Paul's death also means that items featuring him are destined to become collectibles, said Phillip E. Pfeifer, a professor of marketing at the University of Virginia's Darden Graduate School of Business Administration.

"I think we're still going to see John Paul a lot," agreed Roberto Stiller, who has been running his souvenir stand near the Vatican for 30 years. "He was a great one."

Still, within hours of his election Tuesday, several books by the former Cardinal Joseph Ratzinger jumped onto the best-seller list of Amazon.com, including "Salt of the Earth," "The Ratzinger Report," "Introduction to Christianity" and his memoirs, "Milestones," which covers his life through 1977. Many of the books were not immediately available because of high demand.

Eight of his books were listed among the Web site's top 25 best sellers.

At the religious Libreria Ave bookstore near the Vatican, manager Umberto Livadiotti said his stock of 50 books by the pope sold out within a few hours of the announcement that he had been elected.

But he didn't expect that it would last long, partly because the books by the new theologian pope were not easy reads.

"They're not within everyone's reach," Livadiotti said with a smile.

In the United States, at the Catholic Supply of St. Louis Inc., a global clearinghouse of everything from church-related books to clerical apparel and school uniforms, the election of the new pope touched off a flurry of requests, the store's Lara Traina said.

The limited supply of books and pictures of Benedict were gone within minutes of his appointment, Traina said.

Calls flooded in Tuesday with orders for color pictures and prayer cards of the new pontiff, prompting the store to order thousands of the items.
