Where can I find a messenger bag with some sort of decoration/pattern? - large messenger bag

My beloved backpack and a half has irreparably damaged and require a large messenger bag, it is not clear or a color. I want a picture or a drawing or some other device, or the truth, but I do not know where to start the search, either online or in a store. Thank you;)
