They have poster board but no posters with pictures.
They do sometimes have poster boards from which you can make your own signs or use in a science fair project for say the backing 'walls' of the display. Like anything at 99¢ Only Stores, I ts really just hit and miss as far as what they have in stock at any given time.
Sale signs
But for "science fair"
They do not. But they have other decorative items like pic frames, small wall art, etc.
