Hi again. Please take no offense of my writing about this decanter.
First the foot of Your decanter is called "Elco-foot" and was designed by, at that time the CEO, Elving Conradsson. He made this thinner waves for the foot instead of the older
version with thicker waves, if You follow me.
It is often wrongly attributed to Bo B, even in papers like Leslie and Pina, but the only time these cordial/martini decanters can be attributed to Bo B is when they are in
blue and green combination.
