I'm having too much fun with this...
I make the promo artwork to advertise our band's gigs, and do something different (and often seasonal) for every show. I usually just do a Google search for "four _________" with the blank being anything from Easter eggs to old men. I use that image as a background and add our band logo and call it done. Since our band name is a play on "OCD", I try to find a picture with three normal things and one odd one. Sometimes I spend an hour or more finding a workable background image.
For our upcoming gig at the Dragonhorn next Friday, I just selected a blank white background and told Photoshop AI to fill it with "four rocking chairs". It took a couple of tries, but this image ended up being perfect, since the AI engine really botched up one of the four chairs.
