How to darken lines on old drawing (~150 years old, yellowed paper, faint pencil line

[ludicrousliam]

I attached a cropped portion of the drawing (its pretty big). Whats the best way to make the actual drawing pop? (make the lines darker and more noticable) It will be printed and framed when finished so the background must remain aesthetically pleasing

You really don't have much data there to work with. I tried it with ACR and got this.
