Hi Ya Barry,
If you are serious about the matchbooks as a collectible you may consider. If you thought of buying them to re-sell and recoup your investment you may be happy you did not buy them, it's just too much work to catagorize, scan and finally list them for sale. I personally have to try,, really hard,, to stick to what I collect or atleast what type of matchbook or cover I'm interested in.
Like most collectibles the older the better, I love the look and feel of anything vintage but I can't buy it all

Happy Holidays Barry,
Regards,
Eric
