This is an excellent Pinterest board featuring over 500 antique match holders. I just love it.
These other websites also feature antique/collectible match holders. Some are for just for show, while others are serious antique dealers with items for sale:
Also, fellow pyros, did you know there's a name for those of us who collect match stuff? When you go to a fancy restaurant or stay at a resort hotel, do you pick up a matchbook or box of matches and put it in your pocket to use later? Even people who don't smoke or use matches will often pick up a matchbook as a souvenir, especially if the matchbook has a lovely or intriguing cover or a logo of the place it came from. If you are one of the many people who enjoy collecting matchbook-related items, then you are a phillumenist. You see there? PHILLUMENIST. We've been diagnosed and can start our own support group!
