Reveal Sharpie-Redacted Numbers

I have a slightly worn but still perfectly readable sheet of paper on which three key digits were blacked out with a Sharpie. The marker stroke is narrow—only the numbers themselves are covered—so I’m confident the right mix of high-resolution scanning, contrast manipulation, and forensic imaging techniques (infrared, multispectral, or even advanced Photoshop/GIMP layer work) can bring them back.

Here’s exactly what I need:

• A quick, water-marked preview that clearly shows the recovered digits so I can confirm you’ve cracked it.
• After I approve, the final unwatermarked file in high-resolution PNG or TIFF, with the entire document intact and the three numbers fully legible.
• A brief note on the steps or tool chain you used for future reference.

If you can produce the preview fast, let me know your timeline and any questions. I’ll move ahead with the booking as soon as I see those digits.
