I have the original box from my copy of CS2, direct from adobe, and it does, indeed, have a part number on the box. The one thing you might be VERY careful of, is that UPGRADES are sold, implying that they are FULL version. As to trusting something from e-bay... A business, I might. Also, when I did buy CS2, the best price was from Adobe. I believe they have an arrangement similar to AMD.... the legitimate sales only vary minutely, including the manufacturer. Curious thing.... they even took the time to put MY name in the "credits". Lou.
