Vintage restaurant ware ironstone china bowl or handleless cup made by Sterling (USA) china and marked for the Del Paso Country Club Sacramento California.
At least I think this is their emblem, but have never even been to California, and I just ran searches online finding first a matchbook with this crossed golf clubs mark and DPCC, found that was Sacramento, looked for golf courses there and found Del Paso.
I love the old fashioned sporting feel of this piece, in any case! It measures about 3 3/4" across the rim, 2" deep. It's in good used condition.
