So this Speed Limit 69 sign is obviously meant as a humorous novelty item - it's not an official traffic sign, but it looks just like the real thing. It's 12x18 inches, which is the standard size for road signs, made from durable rustproof aluminum. The reflective material is 3M Engineer Grade, which is the same stuff used on actual road signs - it'll light up brightly when headlights hit it at night. The graphics are laminated, which protects them from weather and graffiti - you can actually clean off graffiti without damaging the sign. It comes with pre-punched holes for easy mounting on posts, fences, or walls. SmartSign is the manufacturer, and they've been making signs since 1918, so they know what they're doing. The 3M materials come with up to 7 years outdoor warranty, so this sign should last a long time. It's one of those funny gifts that always gets a reaction - perfect for man caves, garages, game rooms, or as a joke in someone's office. The construction is solid - 63 mil thick aluminum with rounded, burr-free corners. Unlike cheaper signs that use inkjet printing that fades quickly, this uses proper 3M inks that will stay bright for years. Whether it's for a bachelor pad, a fun office, or just as a conversation starter in your garage, this sign delivers that combination of quality construction and humorous messaging that makes novelty signs actually worth buying.
