What's the difference between TSB & OSTSB?

What's the difference between Tobacco Sunburst and Old School Tobacco Sunburst?

Answer from Dave McLaren which he posted on G&L's facebook page:

OSTSB has a light edge, still transparent. TSB has a dark brown edge, where we mist the edge lightly in black.
OSTSB is "old school" because that's how we used to do TSB in the '80s to early '90s
