Lightly sand the surface of the outlet covers and wipe away the dust. This roughs up the surface and gives the paint something to stick to. Spray with spray paint (several light coats) and let dry.
Trace circles to fit your covers using a circle template and the comic books. Alternatively you can use laserjet copies of the pages. You will still use the same process.
Cut out the circles; one for each cover. Dampen each image slightly to make it easier to remove wrinkles.
Apply Mod Podge to the outlet cover; lay the comic book circle on the surface and smooth out, pushing out any bubbles. Repeat with the other outlet covers and let dry.
After 20 minutes, top coat with a layer of Mod Podge. Let dry, lightly sand, and repeat.
Glue the gaskets that come with the outlet covers to the back using the E-6000 – you could also use cork or felt if you’d prefer.

Notes
Tip: if you use color copies, make sure they are printed on a laserjet printer to prevent bleeding.
