I'm wondering if the bellhop in this ad is working at some swank hotel or just insists on dressing like he's in the Imperial German Army. I'm rusty on my Waffenfarbe or service colors but white collar and cuffs I think designated the baggage train troops which would be apropo since he is a bellhop. The 1930's and 40's saw a proliferation of these "storyline" ads which sometimes could have a comic book appearance or at others is like this ad. Gentleman has a great day at the fair, asks the bellhop what's to drink around here. Bellhop suggests Ten High Whiskey, gentleman is pleasantly surprised and gives bellhop a great tip.
The whole idea of researching old advertisements goes beyond just the artwork involved and making fun thereof. It also is funny to see how advertisers would go to great lengths to convince you that their product is the best and you should buy it. Looking at in this light we can see that the more things change, the more they stay the same, only the media used to convey the message has changed.
