That is quite cool, nice find! You mention that it is silver, is that corrosion on it or is it silver plate over a base metal? Any idea on the age?
Edit: I found what looks like your spoon.....circa 1900:

SALEM INTRODUCES THE "SOUVENIR SPOON" TO AMERICA
Salem, Mass
October 1, 1890
Today, Daniel Low, a local jeweler and silversmith, unveiled the city's first souvenir tribute to the witch trials of 1692 -- the "Salem Witch Spoon." The new sterling silver spoon is engraved with a broomed witch, the name "Salem," and three witch pins (eerily similar to those used to prick witches in the 17th century).
Salem draws hundreds of tourists every year to the site of the witch burnings on Gallows Hill, and the souvenir spoon, beautiful and utilitarian, offers a lasting memorial to the city's history.
The Witch Spoon was designed by Mr. Seth Low, son of Daniel Low, after his recent return from the Continent, where he found similar spoons, commemorating European events and landmarks, selling to tourists.
The junior Mr. Low has also introduced manufacturing dies for the production of the spoons. This is the first time die tools will be used to produce fine silverware in America, enabling more efficient production and affordable pricing.
"But," the senior Low assured, "We have not sacrificed quality in our production." The crowd of about 200 citizens gathered at Salem's Town Square cheered Low's words, as it circled the dias displaying the spoons.
"I predict," said Mr. Low, "that the Witch Spoon will be a commercial success and that other American cities will create their own souvenir spoons. In fact, I believe that the 1890's will be the decade of souvenir spoons!"
The Witch Spoon will be sold in three sizes and shapes: tea ($2.00), coffee ($1.25)) and orange ($2.25) sizes. They will be available November1 from Daniel Low & Company and by mail order. Those wishing to order by mail may use the coupon from the ad in the November 1st edition of the Saturday Evening Post.
Daniel Low & Company, Jewelry & Sterling, Gold & Silversmiths, 231 Essex Street, Salem, Mass was established in 1867. For additional information about the Salem Witch Spoons, please contact Mr. Daniel Low at the address above.
