1930-1980? Matchbook cover Denver & Rio Grande Western Railroad ephemera train

Description

1st - I AM NOT A BUSINESS AND DO NOT HAVE POSTAL PICK-UPS TWICE A DAY  so please allow me IF needed an extra day or 2 if needed.
I inherited a large lot of older stamps and have bought a few simply because I thought I knew what I was doing and they looked old. I did buy 2008 Scott Specialized book for some help but I can't figure out most of this. I also am listing some of the large lot of railroad related items including many rare matchbook covers.
Railroad matchbooks apparently have become highly collectible and like anything collectable today, these items may have been common several years ago are getting hard to find as most are now in collections and come up for sale fewer and fewer times. I have no idea of the ages of these covers but I believe MOST if not all are probably from the 1930s-1970s?
Collectible matchbook covers sold by themselves with shipping added will usually cost between -12 so I'm trying to keep these low priced if possible.
I am selling many matchbooks cover and no 2 are the same. Each one is different in even the slightest ways to make them variations.
IF there is nothing on the backs, I will not show a picture.
PLEASE PLEASE PLEASE be patient while waiting for you items. The Post Office is struggling right now and mailing a simple letter can sometimes take as long as a month just to get to your neighbor. I know this for a fact. I believe the buyer has up to 90 days to ask for a refund so PLEASE allow extra time IF needed. Thanks!
PLEASE ask questions before you bid and BE SURE it is what you want so we don't have to go through the hassles and costs of returning. Thank you.
