A list of Illustrators I admire - Definitely NOT exhaustive

Here is a list of my favorite illustrators.
My introduction to these artists were often by book & magazine covers.
They also have thriving fine art careers in other industries.
Besides each artist's name are the examples that introduced me to their work (Just a tip of the iceberg).

Have tried to include official sites. Sorry, I can't STAND Wikipedia.

This, of course, is not a complete list of my favorites and influences. That would take a lifetime to compile, however, I will be posting favorite writers as well.

Also, please explore the sites I provided.
Most of these artists have far-reaching careers and long bodies of work.
Exploring their sites is, pun definitely intended, especially for these speculative fiction artists, like exploring new worlds.
