I hope they are just stage setting for a working class President from the West..where this stuff is more normal wear. Maybe AK.
I think you have something there.
I've seen little signs, here and there, of products referring to the outdoors, ruggedness, and specifically, the state of Alaska.
Safeway (grocery store chain here in the West) has in the past year (I estimate) started carried an "Alaska Classics" line of their house brand of ice cream.
(This reminds me of back in the 1990s when the Safeway store carried a "President's Choice" line of premium items (cookies, etc.) which is today marketed under the "Safeway Select" brand name. At the time the "President's Choice" products carried a signature which looked very similar to that of President Bill Clinton, though Safeway insisted the "President" referred to in their brand name was their company president.)
I think we should set up a ping list or a thread about similar "stage setting" items.
