Late Loetz: Bubble Glass examples.

Bubble glass is among the least appreciated lines of Loetz very late production. So far, no PN's are available [to my knowledge]. They appear with both the oval and the square mark, but most have lost it. Those with metallic blue applications are, on the other hand, overvalued. Yet, those in blue, like mine, all glow bright green under UV, indicating pre presence of uranium. The glass is thick and heavy. The bubbles are quite symmetrically applied. And, no rims [as in Tango, for example]. Apparently, they are not yet considered Loetz [not mentioned in loetz.com], even though the square mark is the Loetz mark.
Gary, the post was for you, since I'm still blocked on FB. I am anxious to hear from other owners and compare notes.
