When updating legacy content, I often come across cases where we never got the original Photoshop files from the designer or it's so old that it got lost many generations ago. So I'll work from an existing JPG and use selections to keep parts of a composition. In the case below, we need to swap out the old logo for "Wiley" and replace with the Akzidenz-Grotesk font. The text was however placed on top of a background that was hard to rubber stamp out. So I kept the 3 square images and recreated the background using filters.
