Toronto. Over a century ago, you could get a cookie size round case for your images. These tiny marvels were offered in the mid 1800s to house tintypes etc.
The tiny union cases came in various colours. This one from Paul Berg is in a lot being auctioned by Cowan’s Auctions on behalf of the Daguerreian Society Online bids are being accepted too.
Since some are rare, you might like to bid and grab a case for your collection.
