You can purchase it from RedBubble! (Where it’s also available as a phone case, poster, or pillow!)
READING IS ADVENTURE
"Every book is an adventure—in this world and so many others. With subtle references to great book series like Harry Potter & Discworld, this is a design for every reader who’s traveled to far-away lands (both real and imaginary) and has a mental suitcase full of wonderful memories and souvenirs."
I’m putting it on sale for $23.40 for the next few days.
