Featured Help with glass paperweights please

Hello friends, I picked up several art glass paperweights today, but need some help with a couple of them.
The first one is a ball paperweight that is signed and dated, but I cannot make out the name at all. I have tried so many different versions of what I think it looks like but came up with nothing.
The second is a glass heart paperweight that looks like it’s signed “Rulb” to me, and it has a “R” in the center of a shield. I did find a vase online with the same mark and a forum asking about the same mark, which someone suggested Rosenthal to them, but I’m not so sure.
I appreciate any help!!

 

isn't that lb, actually the year (20)16?

 

It gestalts for me as Lawson.

 

That would make more sense!

 

Nice weights here is another one that shows the mark a bit better, I don't think Rosenthal either but don't know who. If you don't get an answer here, try this FB group, they are nice and helpful too

First one is probably David Wilson.

 

I think you’re right! Thank you so much!

 

I found the artist of the heart!!
Mariusz Rynkiewicz is the name in case anyone else is interested.

Thank you to everyone for the help and suggestions!
