Illustrator and designer Dan McPharlin gives little information about himself, his work or his clients on his website, which essentially just offers a download of a PDF portfolio from 2006 (also lacking in background information) and a link to his Flickr stream, which serves as his actual portfolio on the web.
In the latter you can browse through his larger photostream, or focus on a set devoted to Selected Work.
He has apparently illustrated covers for a number of audio recordings. Some of his work is graphic and design oriented, but the pieces I find most interesting are his science fiction themed illustrations that have a wonderful feeling of 1960’s Ace/Berkeley science fiction book covers.
There is a brief interview with McPharlin on Sci-Fi-O-rama, from which I glean that he works digitally.
