Here is an interesting bit from Kovels Komments.
A painting was discovered behind the glass in a mirror waiting to be sold at a March 2016 Clars auction. The painting was identified as a picture of Grandfather Mountain in North Carolina by Elliott Daingerfield, an important North Carolina artist. It’s in excellent condition because it has been secretly preserved behind the mirror for over 40 years. The estimate was $6,000 to $9,000. Bidding started at $3,000, and after many bids, it ended in a battle between two phone bidders. The picture sold for a record price of $39,325. The auction house was pleased, the consignor was pleased and the president of Clars joked it was the highest price ever paid for a mirror at Clars.
Look behind mirrors. You never know where you might find good things. Look between the pages of books and behind paintings.
