Apparently my in-laws' garage is not without hidden treasure -- I just stumbled upon two great Star Wars activity books from 1983, and I had to share.
The publisher partnered with Lucasfilm -- they have a copyright notice and everything! -- but even so, this is the possibly the worst collection of officially-licensed Star Wars-related kids' materials I've ever seen.
For your pleasure: the official Darth Vader Dime Bank!
