mid-century vintage ceramic art pottery vases, pair of mandolin musical instruments

Pair of mandolins, vases to hold small flowers, or perhaps pencils etc.. These are about 7 3/4" tall overall, both in very good condition without chips or cracks.

These are mid-century vintage, 50s or 60s. They're not marked with a maker, probably California studio pottery, we think. So many of those pieces had labels originally, no stamped marks.
