That 'SG Standard' looks more like a '61 Les Paul than the later SG if you ask me, they even put 'Les Paul' on the headstock. The original single cutaway LP was discontinued in 1960 and Gibson introduced what we now know as the SG body in 1961 as the 'New Les Paul' (unbeknownst to Lester Paulson, who immediately threw a hissy fit). In around 1963 they started calling it the SG, and retired the LP name until the late 60's when Gibson noticed all of the guitar gods of the day playing ten year old (50's) single cutaway LP's. The other styling cue is the smaller (and better looking in my opinion) pickguard, around 1968 Gibson started using the bigger pickguard with the pickups mounted directly to them on the SG's, bad move.

One of the few things that Les Paul can be directly attributed to (and he demanded) on the original (1952..?) LP's is the wrap-under one-piece bridge, which was totally awkward to use, and was so badly received that Gibson quickly came out with the now standard Tune-o-matic bridge with a stop tailpiece setup. Many of those originals were later retrofitted with separate bridge and stop tails, which ironically makes them less desirable (and valuable) to collectors, but finally made them playable instruments. If only Les was half the genius he thought he was… I know that's going to rub a lot of people the wrong way, sorry.
