New Gibson Banner-era J-45 jumbo flat-top guitar as well as many LG-1, LG-2 and LG-3 models. It is also the correct pickguard for most 50s-era SJ, CF-100 and J-50 up to approx. 1955. After 1955, the SJ, J-50, LG-1,2&3, and J-45 got another shaped pickguard. It's made from a heavy .05" thick real celluloid tortoise shell and comes with 3M adhesive transfer tape backing, so all you have to do is peel and stick it on your guitar. Hand-buffed glossy finish including polished 60 degree beveled edges.
