Mickey's Big Mouth is still a signature of the Mickey's 12 ounce glass bottle...
but the full signature has changed
in my youth the Mickey's Big Mouth Bottle had a very unique pull tab
a tab that I never discovered the proper technique for opening with "coolness"
but witnessed the awkward opening with spillage many times
if I remember correctly I would pin the bottle between my knees
then pull the tab down up then off
the 40 ouncer had a standard size pour spout
while there were various products that had a nice handle on the jug like a big bottle of cider or moon shine
packaging... part of the experience
