Fallout 4 robot build poster DLC foreshadowing?

I can't remember where I saw it, and I've scraped the bsa files, but I can't find it anywhere.

I clearly remember there being a poster or wall hanging in a lab somewhere that showed all the kinds of robots.

Protectron, Handy, Sentry, and a Synth-like robot.

And it showed a bunch of pictures that looked like the results of a body flip book. One drawing had a sentry legs with a synth torso, protectron legs with sentry torso, and so on.

I thought it was interesting but didn't screenshot.

Then the DLC comes out, and I wondered if they dropped that poster as foreshadowing the DLC.

I've retraced my steps everywhere and can't find this poster...

Did anyone else see it?

EDIT: Thanks to the answer, I found it.
