vintage Czech bird figurine figural flower holders, frog style vases collection

Collection of three bird on a tree stump flower holder vases, all Czechoslovakia, 1920s or 30s vintage. These have a lovely smooth semi-matte finish, so pretty together!

They measure about 4 3/4" to 5 1/2" tall. There's some soil marks to the unglazed bottoms of these pieces, but no chips or cracks.
