YEARS: 1960-1963
Box for “Glitter Glo” costumes which had glitter glued to the fabric to be reflective at night. One of the company’s earliest safety features.
“Glitter Glo” was trademarked in 1959 (link) and the brand was heavily advertised from 1959-1962 when it was more or less replaced by the “Magic-Glo” line of costumes.
The box can be seen briefly in the background of this 1962 footage.
