Future World by Steve Perrin 1982 booklet/manual no box, etc.
Magic World by Steve Perrin 1982 same as above
SuperWorld by Steve Perrin 1982 same again as above.
These could be from the Worlds of Wonder box set. A few other items would complete it, namely the box itself, and, well, the BRP rules. If it were complete, it might fetch a decent amount ($30 - 60, but fluctuating) so individually, I don't think you'd get much for them... maybe $1-5, if someone is looking to Frankenstein a set.
Those who can, don't. Those who should not, do.
