I wanted to share this photo of Popkje Boonstra with the community. Location: unknown. Date: unknown.
Click here for the image details page or here for the full-sized version (790 x 1221).
Oldest son Gerben was born in 1920 in Ee, Friesland, Nederland. So I think the photo can be dated late 20's / early 30's, and possibly in Ee.
