1e. Not just because the art, but because it was when dragons could be used throughout the entire campaign life based on the age rating system. You could have a relatively low level party take on a young dragon, and an ancient dragon of the same type would be a tough challenge for a high level party (high level in AD&D being 9-12th level). As mentioned, an ancient dragon's breath weapon would take out most equal level PCs, even if they made their Saving throw.
