Long time geek, fangirl, mother, and reader. I've got a lot to say, you might not like it all, but it will be honest and hopefully helpful.
I read these comic books (and still own them) in single issue form. You can find them in book stores and on Amazon in trade paperback. I think every fan of fantasy should own copies.
Mouse Guard would appeal to any fans of Lord of the Rings and the Rats of Nimh. Not to mention the art in the books is breathtaking and detailed.
I'm holding on to these books with plans to pass them onto my sons once they are old enough. These books are a classic and should be in the collection of every fan of fantasy. I have my fingers crossed for a reprinting in a hardback edition.
