For starters, you can do some research about notable bitcoin personalities. And from there, if there are any cryptocurrency-related events in your area or locality, you could maybe try to get in touch with that notable bitcoin personality ahead of time before attending the said event, so you could at least be assured that you'd be able to achieve your artwork signing request for example.

Maybe, you could do something that's for a good cause also, so there would be a sense of purpose added to what you're trying to achieve in the process.

About museums, since I'm not a handcraft artist, I don't know much also other than try to look for some info online about museums in your area or locality as well.

Either way, these are just ideas I am throwing in to possibly help you out somehow.
