Last week, I came across this in one of the textile collection binders:
Per our records, this particular bonnet was found by museum staff in the pocket of a donated object: a c. 1970s white mink stroller coat. (Also in the pocket was the white leather belt that tied the whole look together.)
There is something very charming about a chance encounter with a personal and commonplace item unwittingly gifted to the museum. (It is fairly standard museum and archive practice to retain secondary materials associated with collection objects.) Art comes from people, after all.
