The symbols on the Autobot poster are a font called “Ancient Autobot” and they read, “Freedom is the right of all sentient beings.”
The symbols on the Decepticon poster are a font called “Decepticon Graffiti” and they read, “Peace through tyranny.”
The Autobot Elite Guard poster also uses the Autobot symbols, and it reads “until all are one.”
The yellow and black is a poster for the Functionist Council. If you’re looking for the Prime continuity, then it could represent Sentinel Zeta’s High Council of 13. The symbols are a font called “Modern Iaconic” which doesn’t seem to be affiliated with ‘Bots or ‘Cons. It reads “Form is function.”
The black and white poster is, of course, the Wreckers. <3 The subtext is also in Iaconic, and it reads “Wreck and ruin” (because I couldn’t find another motto and the whole, “backup and clean-up” thing was too long).
