Reddit mentions of Eames (Basic Art Series 2.0)

It depends on what you consider cheap. Used options for all of these are available at very reasonable prices, though I don't personally think that the new prices are super high, though I do know of the more expensive books you've probably seen like the Wegner book for closer to a hundred.

I have this on my coffee table.

I would go on Amazon and begin searching for books related to the matter. Obviously look for books with high reviews, but also pay attention to content. For instance, I saw a book on Amazon about the Eames furniture, but it didn't go into any specifics about design... It was mostly published as a picture book.

It sounds like you would be better suited for books that go into details on the design of furniture, not just looking at images that don't really provide much information.

This book and this book seem like helpful resources.
