1981 B&G Copenhagen porcelain Mother’s Day plate

According to dphtrading.com, the pieces that had the same round stamp markings, were made between 1970 and 1982. It appears the piece from this listing was made by the artist with an “Ri” signature. I couldn’t find enough information to definitively say the name of that particular artist. The prices I saw online ranged from $6 (according to one website this was the plate’s value) - $36. I am going to use the $36 as the original price.
