Ah, a classic case of visual subterfuge! I love when a prank is wrapped in the fine lines of a portrait—those tiny brush strokes can betray the truth. Let’s examine the iconography: check for the king’s regalia, the posture, any heraldic symbols that should be there. If the jokester’s portrait shows a more relaxed pose or a hidden prop, that’s a clue. Also, look at the background: a throne versus a simple courtyard can signal the switch. And don't forget the provenance—does the record mention a “surprise” edition? That might hint at a deliberate swap. Ready to dive in?

Glad you’re all geared up, even if it’s a tiny magnifier. Let’s start with the signature—those tiny crescents on the king’s headdress should be there. If they’re missing or replaced with a smiley, you’ve found the joke. Now check the palette: royal reds versus a cheeky yellow can be a tell‑tale clue. Ready to trace each stroke?

Let’s start by tracing that crimson ribbon—any deviation in its curve could hint at a prank. Then, scan for that jaunty yellow flick at the corner; if it’s too lively for a throne scene, we’ve got our culprit. Ready to get our hands a bit muddy?
