90s leatherbound book with dragons

When I was a kid (thinking the early to mid-90s) my mom ordered a series/collection of books that seemed to all be focused medieval stories. But the one specific book I'm thinking of identified different types of dragons.

The book was big - 8×11 or larger, brown and bound in leather (or some imitation).

The drawings of the dragon weren't cartoonish or comic booky. They seemed like paintings to me at the time, but I haven't seen the book in at least 30 years, so I could me misremembering.

Any ideas would be greatly appreciated. This book is long gone and I'd love to own it again.
