Yeah, I think that costume in the book is from Return of the Jedi (there are 3 "new" Jawas in Jabba's throne room that didn't re-use the ANH costumes.)
That's how the Jawa faces are in ROTJ (black cloth face screen, fully exposed "large" eye-lights,) and the ROTJ robes don't have the really obvious "off-white paint" weathering that the ANH ones do.
