Question about Postage Stickers
Goodmorning from San Antonio, TX. I am going through some old stamp books, both of which have the stickers here and there. I have a few questions regarding these. What do they have to do with stamp collecting, and are they valued by collectors. All help greatly appreciated. Thank you in advance.

By the way, the blue item is a cigarette pack revenue stamp from the US. Some have argued for some time that it belongs in the Scott catalog.
