Pressed Glass Dot Pattern Salt/Pepper Shaker

This is a neat old pressed glass salt/pepper shaker. The pattern is simple, slightly raised dots that are a bit smaller towards the bottom and a bit larger towards the top. I wasn't able to find the exact pattern listed anywhere but it may be some sort of "polka dot" pattern. The tin lid is decorated with small stamped tulips that circle the edge. The bottom is marked 4-474.

The shaker is 3 1/8" tall and in good condition. The lid has wear consistent with age. A simple but elegant, early piece!
