You are viewing a SET OF 4 CRYSTAL CLEAR GLASS SOUP / FRUIT / SALAD BOWLS.  They measure 6" in diameter and 1-1/2" deep.  They are detailed with raised relief on the bottoms featuring OAK LEAVES AND ACORNS.  The acorns form "feet" on the bottom of the bowls.
These bowls are not marked so I am unsure of the maker or age.  One bowl does have a chip on the rim, which I have tried to capture in a picture.  It is very very small but thought I should mention anyways.  No other chips or cracks.
