Identifying Vintage LEGO Instructions I bought a box of old LEGO from the charity shop and the instruction booklet is missing the front page so, I’m struggling to find out information on it and how old it is! Can anyone help?!
These are instructions from "LEGO Books - Idea Book #1 or 221", that was released in 1973.

YouTuber BrickTsar uploaded his entire childhood book HERE.







Similar to the LEGO Idea books I had as a kid in the late 80's, these types of books were made with multiple sets in mind. 

So, there isn't a focus on one specific set. The focus was you nagging your parents on what was vital for your next birthday.
