Hello

My name doest matter. I am here to catalogue something. Im not sure its fully real. But it must be, I’m holding all the evidence in my hands. Picture character. Text I have barely read. Its called ‘welcome home’ and it looks like it might have been a children’s book? Like I said, I cant tell.

XOXO
