Trying to display post authors

I have a custom post type “Meanings” for which there are multiple authors, or at least multiple people recorded in the “revisions” (maybe that’s the problem?).

I would like to display the authors or revisioners. Here’s the template I’ve created so far.

[before]
<class="related-to">
[/before]
	
	[each post_author]<div class="related-to-list">
	<a href="{@post_author}"><div class="related-to-image"><img src="{@post_author}" class="related-to-image">{@post_author.image}</div>
		<div class="related-to-title">{@post_author.author_username}</div>
	</a>
	</div>
		[/each]
			
[after]
[/after]

There are two possible revisioners attached to the color page I have linked to.

The page I need help with: [log in to see the link]
