Rosenthal Lobster Tableware

We have a few pieces of this set and we're completely stumped. We haven't been able to find a Rosenthal marking that exactly matches. A few pieces of this pattern sold off a swedish gallery website, and a German gallery used a picture of this covered serving dish to market a Rosenthal porcelain event, but that's all I've been able to come up with. Does anyone have any info on when this was produced and what this pattern might be called? Thanks for your help!
