Vintage Montreal Bike Paths Map Restoration

Digital Picture Restoration

9.6•7.1—> that's the size of the picture attached, in cm, on my cellphone screen
(if you were wondering, it's a map of Montréal's bike paths in 1897;)
That's approximately a 3:2 ratio.

I'm hoping for a large print, maybe even 1.3m by 1m.

Here's what I'm hoping for:

A full restoration.
Removing fold lines, creases, tears, stains and other imperfections.
Rebuilding damaged areas where possible.
Improving contrast and clarity, & then upscaling and sharpening the final image for large-format use.

Preserve the original vintage character of the map, so it doesn’t end up looking overly processed or artificial.

I understand small text or details completely missing from the original image can’t recovered perfectly, but from the image I sent, I'm hoping you can achieve a substantial improvement; a clean, high-resolution version suitable for large printing.

A restoration, high-resolution final file.

If I tell you how large I want to print it, can you prepare a resolution specifically for that size?
1.3m by 1m is what I'm hoping for , at most.

I just put any price, but tell me what you would expect for such work.
I'm in no rush.
I just want a good job.
