Kralik ?- Vase

Here are Kralik Question mark Vases Cir. 1930's. I have seen only three colors but they could come in more. If you look carefully you can see talented they were... positioning a glob of glass then rolling it around then down to the base,... and there are three!
There are very few tango types from Kralik that have applications (unlike Loetz)... I suspect there are many application types that get credited to Loetz that are actually Kralik.
