Below are two other Smith's Mello Mint wrappers:
I believe the top wrapper is for an individual stick of gum, while my wrapper (earlier post in this thread) is for a 5-pack.
The bottom wrapper appears to be given out as a promotion of some kind; "unfolded" E105 examples were probably distributed this way.
Many thanks to fellow board member Mark M. for the scan of these two wrappers.
