Sure. Create a new document and make another layer. Drag the new layer below Layer 1. Use File > Place to place the highest resolution image you have on Layer 2. Double-click on Layer 2 and make it a template layer. Click on Layer 1. Now use the pen tool to redraw the shapes in the template layer. If you press Command Y you can work in outlines, which makes it much easier to trace underlying shapes, especially when zoomed it.
Come back when you've got that far and we'll discuss the shading.
If that's really the only source you have you're in trouble. Did you ever use it in a file that was saved as PDF? Did you ever place it in an InDesign file then export a PDF? Did you ever email it? Look into that. Likely one of those sources, if there's anything there, is a much better starting point.
