Swankyswigs were introduced in 1933 but were originally hand decorated then partly mechanical. Those were mostly just lined and later they used a stencil technique to create all over patterns, still by hand. In 1937 they started to use silk screen printing. All were made by Hazel Atlas until 1956 when Bartlett Collins got involved briefly.
I would hesitate to call these the inspiration for anything without corroborative evidence. For one Swankyswigs started in 1933 but other companies had been hand decorating (brushes and rubber stamps) tumblers since the 1920's. Of course, transfer printing had been available for some time but theis type of glass was characterised by bright lively colourings... mostly dots and stripes.
Once mechanised, it was a means of producing a new look and no doubt put a lot of noses out of joint as the cheap colourful glss must have hurt traditional production techniques... but we are well aware of the impact of lower cost production on glass production.
