Thank you for the reply Secret! It's amazing how much detail has remained on the reverse. I came across a website that had this example...

This one looks very much like mine and was created due to a mis-fed sheet causing extra ink to be placed on the bed of the printing press. The next sheet then picked up the ink on the wrong side. So it was actually printed on the reverse rather than bleeding through. Do you think this could be a possibility as well?
