There were a lot of fake headlines and cutesy jokes floating around yesterday (April Fools’ Day, in case you were blissfully unaware), but you may have missed this one: Canada’s official library and archives released the personal journals and military records of one James “Logan” Howlett, better known to X-Men fans as Wolverine. Among the newly-”declassified” documents are some interesting facts about the famous mutant, including details on his time as a fur trader and a miner.

Library and Archives Canada released the info via their website and Facebook page, along with an old sepia-toned photograph of Wolverine (he hasn’t aged a day!) and an attestation paper for the Canadian over-seas expeditionary force:

As far as April Fools’ jokes go, this one is pretty entertaining — not so much a joke as a fun acknowledgement from Canada of their most famous superhero. Among the facts offered by the archive: Wolverine served in both World War I and World War II, served in the CIA during the Cold War, and spent some time working as a fur trader; the latter of which sounds like a much cooler version of The Revenant.

We’ll see Wolverine next in The Wolverine 2, which re-teams Hugh Jackman with director James Mangold and X-Men co-star Patrick Stewart for Jackman’s final big screen outing as the iconic hero. That film hits theaters in 2017. Meanwhile, director Bryan Singer has been playing a bit coy about the chances of a Wolverine cameo in X-Men: Apocalypse, but you can keep your fingers crossed for a surprise Jackman appearance when the film arrives on May 27.
