Now Dan Zimmer of Illustration Magazine has written a lavishly illustrated book about him (information here). I am quite pleased with it. Some books on illustrators lack details regarding their subjects because illustrators, like many writers, can live somewhat isolated lives due to the nature of their work. Sundblom ran a commercial art studio in Chicago, so there were many people around him that could provide stories. Also, he was quoted in interviews, which helped Zimmer to provide a more rounded portrait than he was able to do in some other cases.
For a quick take on Sundblom, his Wikipedia entry is here.
I posted about him here on 27 February 2012 and here on 8 June 2011. In the latter post, I stated:
"Yet something bothers me just enough that I can't place Sundblom with contemporaries such as Dean Cormwell, John La Gatta and Mead Schaeffer. Maybe it had to do with stereotyping or pigeonholing by clients and art directors. Perhaps it was Sundblom's preference. In any event, the result was that little of his work had drama or "bite" of any kind."
Some of the illustrations in the book invalidate what I thought back in 2011. Sundblom was quite able to paint in styles other than the buttery sort that he is best known for. Some examples are below.
Haddon Sundblom was really good.
