Vintage Watch Advertisement

I found an advertisement of my 1938 Longines Hour Angle in Polular Avaiation (dec 37) and bought the mag. I would like to display this advertisement with the watch when I'm not wearing the watch. The magazine is in rough shape. The question is, do I remove the page with the Ad. and put it in a plastic sleeve for display purpose? Do I mount the magazine with the advertisement page open in a shadow type box? Do I leave the magazine intact, closed on the shelf near the watch.? Opinions are appreciated.

Cut it out and have it framed. They look great hanging on the wall and it adds to the value and helps preserve it. No advantage to keeping it in the magazine.

I have quite a few framed ads in my office.

And 😲
What a watch!!!

Can you post an image of the ad?
