If it's not a Photoshop pic you're thinking of, it could be just a simple variant. There are a number of Oakley models released without embossings, printings or etchings at the start but are added later in it's life. For instance, the first GCs did not have the word "Gascan" embossed on it; the original GITD Frogs did not have the Trevor Andrews printing; and the first wave of the Chantry Hijinx did not have the model number print on it. Other than that, there typically isn't any other diffence, though in some cases there are some minor changes along the way As well (e.g. Dimples in the back of the bridge rather than being solid).
