What should I do with a deceased friend's matchbook collection?

He collected matchbooks for at least 6 decades. He died a few years ago and his wife is finally getting around to cleaning up his stuff. She knows I have a wood burning stove and can always use matches. That is true. I go through a book a week. So she has been giving me bags full. That is nice but I already have plenty.
I can’t bring myself to use the old matches. I feel like they are history. Some of them have the flint on the open side. Some have phone numbers that begin with letters: SUssex 1 5678.
Some of the ads are so interesting. I know I can just use them but I feel that is almost blasphemous.
What should I do with them? I am open to suggestions.
