The NYT's T Magazine has a nice portfolio of artists' depictions of their own kids. It's sort of a grab bag list, a little London-heavy perhaps, but still worth every click. John Currin's painting of his daughter is uncharacteristically sincere. And though they could not be more different, Marco Brambilla's and Nick Waplington's photos of their sons both do that uncanny thing kids' portraits do sometimes, giving you a glimpse at the future adult padding around the house.
This one is by Rob Reynolds, a 2008 watercolor of his 4mo son Sam. The correction and image swap mentioned in the caption has me imagining Reynolds painting with one hand, with a kid on his lap, which may have happened!
