Perfectly acceptable + vintage Lego booklet from 1973. Some wear to the edges. The centre page is a little loose. The vintage LEGO Idea Book 221 from 1973 exists in a variation that does not have the number printed on the cover. The number 221 is the set number assigned to this particular "Idea Book #1". LEGO has often varied its numbering and printing on instructions and idea books over the years and across different regions. It is common for this specific book to be referred to simply as the "Lego Idea Book 221" or "Idea Book #1", with some printings showing the "No. 1" on the cover and others omitting it.
