Vintage Angel Christmas Ornaments Folk Art Hand Painted Ceramic Signed '90 Marin

Beautiful, artisan ornaments that looks to be made of clay and coated in a clear resin. They each have a meal loop at the top for hanging. They have 3D details, some etching and are hand painted. They are in nice, vintage condition with some crazing to the resin (see pictures). I can't read the signature and couldn't figure out the artist. Measurements ~ 2.5-3.25 x 3.75-5.5"
