I'd consider calling this the gilded age of comics. I've been asked from time to time if this is a good era to start collecting as an investment. Generally, I answer "no". However, I usually point out that if the buyer is interested in a great story and great art, then there has never been a better time to get into comics.
And so I call this era the 'gilded' era. While the books aren't any more valuable, they are lined (on the inside rather than the edge) with gold.
