How do I frame art with lettering overlay?

[L Jamal]

I'm doing a comic book art show in November.
For the show, I have 3 types of comic art
1) Original Art with lettering on the board.
2) Original art with no lettering on the board (digitally lettered)
3) Digital art with digital lettering

1) is ready to frame as it is.
3) will be printed at original art size (11 x 17) and framed

My problem is 2).
I could treat them as 3) and just print out the art and frame it, but I really want to show the progression from pure original art to digital and the merger of the digital and analog.

Any ideas that don't involve permanently altering the original art boards?
