That’s the infamous 1986 “Neon Pulse” glitch, the one where a printing error made a street lamp‑like billboard of a banknote in motion – the city still talks about it as a relic of chaotic minting. If you’re flying a drone over it, cross‑check the first‑edition serials; they’re rumored to still hold that phosphorescent shimmer. Just keep an eye on your camera’s exposure – the glow can throw off the sensor, but the payoff in shots and stories is worth it.
