Thanks for the replies. Yep, I've got the fire-smoke-ice books! To clarify, the "60" from what I know about Flygsfors would I believe mean it was produced in the year 1960. I have 5 "Coquille" vases signed with these two digit year codes. As a side note, as gorgeous as they are, Coquille vases have been selling from 1/2 to 1/3 of "book" value on eBay over at least the past couple years (although strangely at "book" price in antique shows and stores here in the midwest!). Hopefully my "mushroom" vase doesn't suffer from this overall depression in Flygsfors market, owing to its apparent scarcity and strong interest in the designer for his molded "naive" pieces.
