Can anybody tell me what this mark is?

Hello:

I purchased a "pair" of porcelain shells with a narrow cactus branch with pale yellow flowers on it.  The dealer had a tag on them that stated they were Meisen circa 1900-1910.  However, on showing a photo of the mark to my sister, I was informed that this was not Meisen.  I have been trying to find the mark online but have not been successful thus far.  I did find a dealer who sold a piece with a similar mark, but she was not able to correctly identify the mark.  One of the marks looks like a signature, and the other looks like it could have evolved from the signature but it is only lines.  I have attached a photo of the bottom of the shells showing the marks.  Does anybody know what it is?

Thanks.
