Don the Beachcomber Rum Barrel Brown and White by Royal Haeger
in 11 collections
This rum barrel from Don the Beachcomber has a white glaze, rubbed away in spots to let the brown underneath show through. "Rum", "Don the Beachcomber" and "Barrel" are in recessed letters on the front. Marked "Royal Haeger" on bottom. Likely produced from 1950s to 1960s.
