This set of glasses only came to light recently and is believed to post-date other sets. They feature circular club logos with the club’s nickname also printed on the glass. .
Once the WAFL had done away with the old “w-style” logos, they moved all their products across to the “shield-style” logos. These were used almost exclusively through until the marketing opportunities died off when the Eagles started in 1987. But what most people don’t know is that there were two types of shield logos. And the WAFL used the alternative logos on the new glasses, featuring cartoon-style mascots.
