EDIT: I forgot to add a screenshot. Here it is.

While re-watching DS9 S1:E19 “Duet”, I noticed this okudagram around 6:21 and got a bit curious.

Some of these images just look like aliens they would have already had pictures of. However, two stand out as potential easter eggs - the picture on the middle left looks unmistakably like Spock, and the human on the bottom left looks like they could be a production worker or a favorite musical artist.

However, Memory Alpha and a simple Google Search don’t seem to turn up anything. I’m intrigued to know what history, if any, is behind this graphic.
