Vintage Ocean Liner Silver-toned Bar Brooch - RMS Queen Mary?

Description

This vintage pin looks to be the R.M.S. Queen Mary. The graphics, the style and the clasp are good clues as to how long it’s been around.
She sailed for the last time in 1967 and was docked in Long Beach, Ca.
In 1972 the Queen Mary Museum and Hotel opened it’s doors as a tourist attraction. Whether this piece came before 1967 or after the reopening, I honestly don’t know. However, it is old/vintage, very cool and a man or woman could wear it
Measures 3 1/2” x 1/2” (picture is 1/2” x 1/2”), weighs 5g
