EASTON, Pa. -

The Crayola Experience has become quite an experience for history buffs.

While digging as part of the expansion for the Crayola Experience expansion project, crews unearthed some artifacts.

The findings include 13 or 14 bones, oyster shells, an old coin and pieces of pottery.

The bones were determined to be from an animal, and officials say the location used to be a butcher shop.
