I found a set of incredible vintage posters advertising bicycle brands: Peugeot, Sirius, Gladiator, and Wonder. What else could I do but design over the shoulder bags that could be used as messenger bags, bicycle bags, or bags to carry your laptop in! This bag is totally lined and both materials, inside and out, are waterproof. The dimensions of this bag are: 15" side to side, 14" top to bottom, 3' side and bottom panel, and the strap is 40" in length & 2" wide.
Look through the posters above and select the image(s) that suit(s) you! Upon request, I will make a bag to your specifications! All you have to do is ask. It's as easy as that.
