While trolling around the Utah Digital Newspapers I found this gem, from the Carbon County News (1914).
Now that is one scary costume.
But the author follows it up with some advice for people on Halloween which is a real interesting comment which I highlighted below.
For those of you who do not know where Carbon County is (I certainly did not) it was south and east of Utah County. I believe this item however was a syndicated column so it may not be local in origin.
Carbon County News January 1st, 1914, page 5.
