Simple question, feel silly for asking, but thought I would anyway.

Are pieces aimed for the gallery allowed to have text on them?

I'm currently working on a four panel piece that showcases different weapons from a popular video game. Of course the focus of the piece is the weapons themselves, but I thought I'd include a tasteful quotation in the panel of each weapon from their respective wielder to reduce empty space.

That sound like something that's okay? Or are there any alternative suggestions? I have considered transparencies, but I think it takes away from it all.

Sorry to be a bother, and thanks in advance.

Thank you
