Kirks Folly Snowman Brooch

This was my charity shop find today. It is a Kirks Folly Snowman brooch signed on the back. It's the first Kirks Folly brooch I have found, so I've been reading up about them. Started in 1979 in New York by 3 sisters and a brother, they have been making lovely fantasy jewellery until 2014, when it closed, though I believe some is still made. I think this brooch was made in the 1990's, but I have only found one mention online as to when it was made. It came in a pink box with a sticker made in USA in it.
