Pattern: Diamond point or “hobnail” texture (raised diamond grid pattern).

This style was very popular in the 1950s–1960s, used for whiskey or cordial decanters.

• Stopper: Original, matching glass stopper with a natural cork insert — a good sign of authenticity.

• Base markings:

• “58” = Year of manufacture (1958).

• The “I inside an O” symbol = Owens-Illinois Glass Co. logo.

• Additional numbers (like “5,” “3723,” or “D-126”) identify the mold and factory location.

• “Made in U.S.A.” confirms domestic production.

• Shape: Square bottle with short neck, typically used for whiskey or cologne decanters.
