mid century vintage West Germany art pottery vases, yellow birch tree bark mod design

Lot of two vintage German art pottery vases, textured like birches in brown and yellow gold. These are numbered and marked W Germany, maybe Scheurich or Bay? They are 5" and 7" tall.

These are both in good condition, a few marks and spots on the bottoms, but not a lot of wear to the gold bark design, and no chips or cracks.
