Besides the obvious, I noticed the marking of "Chicago Match Co.," I would think matched might be produced by different companies from time to time for the same business. Is that an important point? Getting exampled for each of the match companies that produced them with the same printing.

How many match companies are 'out there'?

Many years ago I collected a number of matches (and ashtrays) from casinos I visited but before long I lost interest and the collection went no where. I also kept chips and that collection held my interest.
