I thought the studio 50s tribute was released around 2010, not before

Hi! I recently acquired a Gibson LP Studio with P90, heavy, and obviously from the 90's (serial number is tricky for the year but not the decade) and I was wondering what model it could be. I think there were no reissue with P90 from that era, so I thought it could be a gem serie, but there's no gem logo at the back of the guitar. The paint is very dark, but I know some Gem are too, but I really can't see it a bit of purple or green inside (amethyst/emerald gems paint). It doesn't seem repainted. Could it be a gem without the logo? is there other model with p90 and cream/gold parts from the 90's?
