The Waldorf Astoria is calling on all sticky fingered guests who stayed at the historic property before 1960 and checked out with a few items that didn't belong to them. In what it's dubbing an "amnesty program," the hotel said it is simply interested in getting stolen items back such as utensils, ashtrays, linens and metal room keys, so that it can display them in a special exhibit along with the story behind the theft. Thieves will not be held accountable. The amnesty period will run to Sept. 15 Part of the program's goal is to get more people buzzing about the hotel on Twitter, Facebook and other social media outlets. "My hope is that we'll get some human interest stories that we can share on twitter or Facebook" said Matt Zolbe, director of marketing. On July 1, the hotel will launch a Pinterest page where it will begin posting photos and promote the program. Opened in 1931, the hotel has a historical gallery called "Host to the World" located off of the main lobby where it displays artifacts. It keeps track of its cache through its digital archives at www.waldorfarchive.org . Over the years guests have stolen everything from tiny demistasse spoons used during the hotel's supper club years from the 1930s to the 1960s to even elaborate grills covering heating and air conditioning vents. "People would literally have to have a screwdriver or tool belt to remove some of this stuff, including brass plates on the door lock," said Mr. Zolbe. Waldorf Astoria executives debated whether to offer a financial incentive for people to return the items, but in the end Mr. Zolbe said he was against it because "most of the items were stolen." A year ago, the hotel hired its first social media manager, Meg Towner. The hotel has 3,608 twitter followers and 13,129 Facebook friends. "We'd like for this program to start conversations," said Mr. Towner.
