Cap Badge, American Export-Isbrandtsen Lines SS Co., Officer

Ca. 1964-1973. Cap badge for a senior officer on an American Export-Isbrandtsen Lines SS Co. ship.  The flag has no hallmark but is consistent with the time period.

From wikipedia:

"Jakob Isbrandtsen formed the American Export-Isbrandtsen Lines in 1964 by merging his two shipping companies. [...] In 1967 Mr. Isbrandtsen formed American Export Industries, a holding company to manage American Export-Isbrandtsen Lines and all support for his fleet operations, including container services, port operations, and fleet logistics. In 1971, American Export Industries spun off its holdings and returned to being the American Export-Isbrandtsen Lines. This merger ended in 1973."

The cap badge remained in force through the 1960s.
