Søholm Denmark, EJ64 Krukke//Crock.
This large piece is from the EJ64 series by Einar Johansen for Søholm Denmark in the 1960s. I found it recently at an auction.
The unusual form which I haven’t come across before was designed to be used as a food storage crock or cookie jar by the look of it.
Subsequently it is quite a large, heavy piece.
