Fenton Hobnail Milk Glass Basket.

Manufacturer and Era: These baskets were made by the Fenton Art Glass Company, a prominent American glass manufacturer. While Fenton produced various forms of glass, their Hobnail Milk Glass line, including baskets like the one pictured, was particularly popular from the 1950s onwards.
Distinctive Features: The most recognizable feature is the "hobnail" pattern, consisting of raised, button-like bumps covering the surface of the glass. The basket also typically features a ruffled or crimped edge and a handle, as seen in your image.
Identification: While older Fenton pieces might not have a distinct mark (using paper labels before 1970), later pieces from 1970 onwards often feature the "Fenton" logo in an oval or an "F" in an oval (for molds acquired from other companies) on the base. The quality of Fenton glass is generally high, so major flaws like significant air bubbles are rare in genuine pieces, unless marked as a "second" with a star or flame symbol.
