Scandinavian pottery - What should I read?

I would like to increase my knowledge of Scandinavian pottery. I'm particularly fond of the work of Tapio Wirkkala. I just sold a wonderful Winterreise coffee set he designed for Rosenthal. Also handling lots of Arabia. What are your top 5-10 picks for titles? If the book is one I should buy and have on hand for reference, as opposed to getting from interlibrary loan, pleas let me know by putting "buy" next to the title. Thank you!

I don't know why this photo posted sideways.

Hi, just going to move this into the General Pottery Discussions group which is more suited for this sort of request

It's a while since I used to deal in Scandinavian pottery and glass so there might be other books out there. However, the book I have used since it was published in 1989 is Scandinavia Ceramics & Glass in the Twentieth Century by Jennifer Hawkins Opie. It was published by the V&A Museum here in London, UK but you can pick up a copy in the States.

I still use it and did so earlier today so I would try and BUY, as it has images of items.

Thank you.
