A interesting quote I ran across regarding the announcement by Northwestern National Bank (or possibly it was called Norwest Bank by then) regarding why the weatherballs were being discontinued was because they "no longer matched the bank's corporate identity."
Well, in 1954 the Richfield News ad reports Mr. Weatherball has a new location at 78th and Penn. He now has a treasure chest that only a "Magic Key" can open. Apparently all the residents living in Richfield, Bloomington and Edina received a "key" in the mail but only one would open the treasure! It was the "Magic Key"! What was in the treasure box you ask? Well a treasure...it contained more than $10 cash! WOW!!
