(CNN) A reward for missing artwork -- including Rembrandts, a Vermeer and sketches by Degas -- will decrease by $5 million when the clock strikes midnight on Sunday, December 31. The 13 pieces of art were stolen from the Isabella Stewart Gardner Museum in Boston in a daring 1990 heist. The museum doubled the reward over the past seven months -- from $5 million to $10 million -- in an attempt to entice anyone with information to come forward. All along, they have said the reward would revert to $5 million at the end of the year. "Typically in art heists, works are found shortly after the theft, or oftentimes a generation later.
