I picked these spoons up for $10 in an antique store in Seattle’s Greenwood neighborhood about 15 years ago. I was told they were Russian, but it turns it they’re guilloche enamel spoons made by Egon Lauridsen of Denmark.
Not sure what era they’re from, but seems like other people’s best guesses place them in the 1940-1960 range. While Russian spoons are usually haunted, Danish spoons go through a fairly rigorous exorcism process before they are sold on the open market, so they’re probably not haunted.
