I feel very fortunate indeed to be the owner of this vase, a big big beast at 48cm tall! It was designed for exhibition in 1970 by Per Lütken for Holmegaard, and is fully recorded in his exhibition workbook (Form 2386). A very small handful of them would have been made to buy at the exhibition itself, and it was not put into production afterwards.
The design is completely free-blown, and is a malström of colours and bubbles.
