gibson epiphone sunburst

how can we tell if my brother’s guitar is real?
ok so it looks exactly like a gibson les paul sunburst except it say’s vintage on the head and it doesn’t say les paul in between the tuners. is it real or is it a knock off because it’s definitley not an epiphone because it doesn’t say epiphone on the guitar
if it doesn’t have a Gibson badge or a Epiphone badge its a Gibson lawsuit in the making, ask Ibanez how that works. someones most likely removed the Epi badge on it thinking no one would notice its not a Gibson, for a guitar maker copying that particular guitar is bad news if you want to stay in business.
