Common giveaway mug from Trader Vic's, a brown coconut with white interior, raised white letters saying "Aloha!" on the front, with raise white letters saying "Trader Vic's Since 1934" on the back.

Earlier Trader Vic's Aloha Coconuts did not have "Since 1934" on one side.

There have been several manufacturers over the years and many variants with bottom markings. In general, the earlier Aloha Coconuts were also lighter and a more reddish brown as well.
