Lovely Old Miniature Folk Art Crib with Curious Copper Lining

I've got a weakness for the crib as a form--nice long lines plus pretty arches on the rockers below and head and foot boards at either end. And I think this is a lovely old one, with a curious copper lining, the purpose of which I am not sure, but which was carefully crafted to fit snugly inside, and which can also be removed as one piece. Perhaps to be a mini planter, or to hold cigars! 8 1/8" l x 3 1/4" w x 4 15/16" t. One repaired horizontal split to the headboard, as documented. Otherwise good condition, with a nice patina and nice bleed around the old iron nails.
