For those who didn’t know this yet, eBay is a great source to find LEGO Idea Books, (alternative) instructions, LadyBird books and more!
As an example we found these two great auctions!
The various LEGO Idea Books provide many alternative instructions which you can build when you own the basic (Pirates?) bricks.
And who doesn’t remember them? The Ladybird comic books!
Of course you can find all kinds of written LEGO stuff on eBay, if you lost your instructions just type in: LEGO instructions + set number and if you are a bit lucky you will find one or more sellers!
