There is such a thing as an artist.
Artist: Known — Illustrator for 'A Wrinkle in Time' gets long-overdue credit
Richard Bober is being credited for this cover art based on his related artwork, what remains of his personal archives, and his agent, Jane Frank. Family references include sources from his brother Leon Bober and nephew Matthew Bober, supporting this credit as researched by Amory Sivertson with Ben Brock Johnson presented in an interview on Endless Thread.
Thanks to blogger Sarah Elizabeth of Unquiet Things who jump started the topic asking about this uncredited mystery, Endless Threads producer pulled at this string as well, from publishers Dell and Doubleday to people, eventually to family and Bober's agent. When search engines and library stacks and L'Engle's own archives floundered, Amory reached out to even more people, doubling back and including the research of S. Elizabeth, who recently published comments of provenance left by the family on her blog.
Slides unearthed from Richard Bober's digital archive, as transcribed in the radio program:
Ben (reacting to a picture of slides): Oooo. So I see 4 paintings here and they're VERY cool. There's like a shark swallowing a person and the person's feet are sticking out. There's a painting of two hands holding up a television with a super creepy image on it. And... there's the painting! There it is! In all its glory! And it totally fits stylistically with the others. Like, this is clearly the work of one artist. And one really talented, kinda spooky, artist. It's really cool.
Madeleine L'Engle might take this opportunity to remind us of the power of names. "If someone knows who he is, really knows, then he doesn’t need to hate. That’s why we still need Namers, because there are places throughout the universe like your planet Earth. When everyone is really and truly Named, then the Echthroi will be vanquished.”
