I usually send one or two so you should be fine.

I have no problem asking for two, although there are some who will only sign one - check feedback on here, they're often flagged. If I'm sending more than one I'll generally ask in the letter if they can sign either or both (I generally send two). I doubt there are many who would not sign one because you've sent two, you're more likely to get one back unsigned.

Yes, you can ask for two autographs if you'd like! For me personally, I like to request four from each person I write to, mainly because I plan on passing my collection down to my future kids, so I'd like to be able to give one to each of them. & many have been happy to sign all my items that I send.

Is this acceptable? And are they likely to fulfil a request for two or is this asking to much

Cheers
