My Grandmother was a talented artist (not in any way "famous"!), but I still maintain that she should have been!

My Gram sketched it in the late 90's, and passed away in May 2001, so (for me and my family) there was never any political connotation. I recently discovered it buried in an old box of art supplies...she'd evidently set it aside for framing but never got around to it.
The thing is... It's really wonderful.... If it had been a sketch of the Chrysler Building or any other NYC landmark, it would already be on my wall. However, there's so much "stuff" around the Twin Towers (and I'm deliberately using "stuff" because I don't want a political/religious/moral connotation), that I'm hesitant to display it. On the other hand, it's a really wonderful display of my Gram's love of art.
To answer the first question that will come up...Yes, I have other pieces displayed, so I don't need to display this to remember my Gram. This is just a cityscape from across the river, the Towers are just part of what she saw.
So... WWYD? Frame it and hang it without making a big deal (probably with other black and white photos or drawings...haven't worked it out yet)? OR should I just preserve it for personal family history?
