How can I display ASCII art in two columns on my terminal?

OK, strange question. So I am using fish as my shell and at the end of the shell, I run this cool script that displays a large ASCII image from a video game. What I would like to do is run the script twice (two different images) and have them display side-by-side instead of on top of each other. I’ve looking into the column command but cannot seem to get it to work.

What would be ideal is if I could get two columns at 50% of the terminal width for each image.

Any help is appreciated.
