I believe these may be vintage Imperial but am not positive. The set has a “bubble foot” design at the base of the shakers. They would even go well with the Anchor Hocking “Boopie” glassware.
The shakers measure about 3 3/8” high with the top on. The tops were silver plated possibly but It has come off. The glass is in good condition with the pepper being a little “foggy” probably from the pepper it held.
