|First appearance||Mario is Missing! (1992)|
The Brass Plaque is an item in the DOS, SNES, and Deluxe versions of Mario is Missing! It is the inscription facing the Acropolis on Hadrian's Arch. It is stolen by some Koopa Troopas when they invade Athens; this causes the arch to close down. The plaque is later retrieved by Luigi after he takes it from a Koopa Troopa walking around the city, and he then shows it to various Athenian citizens. They tell him various facts about Hadrian's Arch, such as how it separated Athens and Hadrianopolis (although in reality, no actual proof of two divided cities has been found). Eventually, Luigi gathers enough information that he is able to return the Plaque to the Arch's information booth, and is rewarded $1350.
The Brass Plaque is nonexistent in reality, with the inscriptions that the game depicts as being on the plaque actually being carved directly onto Hadrian's Arch.
- Boy: "His arch divided the city into two. Greeks got one of those plaques and the Romans did too."
- Tourist: "That plaque says, "This is Athens". Its twin says what that one doesn't."
- Reporter: "Take a cab to Hadrian's Arch and put the plaque back, Jack."
- Scientist: "That bronze is from the gate built in 131 AD to divide Athens from Hadrianopolis."
- Policewoman: "That's a plaque from the west side of Hadrian's Gate. Perhaps your brother is stuck in Hadrianopolis!"
