My dad has been getting more into Lego recently since playing with all of our sets. Here's some stuff he's been building and showing us. Some of it is SO old, but still pretty cool I guess.
His Millenium Falcon.
He changed around the inside because he said it needed more detail.
He rebuilt one of his old space sets - LL928.
And these are a bunch of his old instruction books from back when he was a little kid.
