These glasses are ‘swanky swigs’- and they are collected by my partner. Originally the glasses held Kraft products and had a metal lid: then Kraft hit upon the idea of decorating the glasses in a range of themes- so making the glasses collectible. The term ‘swanky swig’ was coined to denote the [obviously] swanky glass from which one swigged! Each design came in six bright colours to form a set; an early innovative use of repurposing.
These swanky swigs have a distinctive Australian theme: eucalyptus flowers & gumnuts, and waratahs. They are getting harder to find now- I think because the glasses were considered fairly kitschy when first produced and many glasses were not kept. But for nostalgic collectors- nirvana consists in obtaining a complete set of six. If anyone has the dark blue and yellow gumnut glasses- I need to talk to you!
