In reply to Jabbott:
You obviously don't have enough CC guidebooks...
The majority of the CC South West guides have had gold titles since 1988.
The 2000 two volume West Cornwall guide, the 1997 Wye Valley guide, the 1994 Lundy guide, the 1992 Avon and Cheddar guide, the 1991 Bosigran & 1992 Chair Ladder guides and the 1988 North Devon & Cornwall guides all had gold titles on black.
The colour on the 2000 North Devon and Cornwall guide is really nondescript but may have been meant to match the gold of the others.
The 2004 Avon and Cheddar guide, doesn't have gold titles but it has bright yellow.
Prior to that, the Lliwedd 1966 reprint, the last of the early hardbacks, had gilt titles. Also the original three CC guides were produced with gilt titles and dark covers.
