How many boards do u want to make?
If you need 5 or less, it might be worth it to:
Scan it on a PC photo scanner
touch up dirty spots with with graphics program
convert image to 1 bit black+white
print out with laser printer (same dpi as scan)
iron onto blank copper board with hot iron
dissolve and remove paper.
then etch with chemicals.
