Lyra's Oxford by Philip Pullman

Like Once Upon a Time in the North, this book features a short story starring Lyra and Pantalaimion and a number of illustrated souvenirs relating to the story. I enjoyed the story, but once again, there's not a lot there. Something to sate hard-core fans of His Dark Materials, rather than adding substantively to the story or the universe--I don't think it would be entertaining for those unfamiliar with the main trilogy.
