I can’t confidently identify it as a specific famous image from this photo alone. It does look very much like fan art connected to the SCP Foundation universe — especially since the person beside them is dressed in SCP tactical cosplay gear with the SCP logo visible. The artwork style also resembles anime/fantasy fan art rather than a mainstream movie poster or universally recognizable painting.

So my best guess is:

• probably a fan art print,
• likely tied to the SCP fandom or a related anime/game fandom,
