LARGE LOT of 24 DeVry Technical Institute radio electronic LESSONS SET w/ BONUS

Description

hello i am listing this large lot of 24 different devry technical institute lesson books for bid. this would be a great chance for a collector or reseller to acquire this many of these at 1 time. with your bid you will acquire this INSTANT COLLECTION of 24 of these! these books also come with 2 cardboard slipcovers that are labeled with the devry logo on them. these booklets all will tightly fit into 1 of the slipcovers.....but i am including a second one as a bonus. this is a great chance for a collector who saves these books to get an EXTRA slipcover to use for books they may already own that are missing that cover.......MOST OTHER SELLERS OF THESE SAME BOOKS ON EBAY DO NOT HAVE THE SLIPCOVERS TO GO WITH THEM.....
condition wise these books are in great shape in all ways except 20 out of the 24 of them are missing their back covers or last page.....im not 100% sure but the last few pages of some of these books have tests printed sideways for a student to fill out.....but my guess is maybe the last page was the final test and after the less the student filled that out and tore last page out and handed that in? even though the last page is missing from 20 of these the lesson that each book is trying to portray is not harmed. i am mentioning this defect to be honest but in all other ways these books are clean and this does not affect the usability of the items. someone can still read these and learn and get full use of them for what they are worth!  these old school lessons on particular subjects are becoming great sellers especially in the old electronic, engine and metal working fields. some people seek out and search this old knowledge for a way to learn the real way, and the old way to accomplish tasks, start a hobby, or start a business. old instructional manuals are a great way to learn real knowledge that may not be printed or explained this way anywhere else!
