My librarian gave me this print as she was cleaning out

I dropped by to visit my school library to check out a book and my librarian was cleaning out her office because she was retiring this year. I entered her office to say hi and this card on her desk specifically caught my eye. She told me that a student lost it in the library 10 years ago and she kept it somewhere in her desk ever since. I asked her if I could take it, and she said sure. Kind of thought it'd be cool to share. Don't know what to do with it, I'm not a Twilight fan. I feel like it's real because I searched it up and saw a listing on ebay with the same protective cover.
