ATAT Driver rotj palitoy bubble variant ?

Has anyone seen this bubble type on a ATAT Driver before ? .... looks like it could be the same bubble type used for the chewbaccas ?

Saw this pop up on eBay yesterday, I was tempted as I don't have this card/bubble combo but has a sizeable crack obviously. Not seen one before but then again I haven't looked that hard. Toni had a few of these cards but normally you'd expect the condition to be better (and not sure if he had those bubbles). I think in reality Palitoy were happy to whack whatever bubbles they had to hand on the card to get the stock out of the door so there are probably a good few floating about. I have noticed that Palitoy seem to have done this especially on these 65Ds as I have 4 different ones...

All Palitoy 65D mocs with (from left to right); Trilogo etched bubble, Trilogo non-etched bubble, double stem bubble and no stem bubble.

Yeah is a shame about that crack , would of gone nicely in your run , I must admit I haven't seen this type of bubble for this character before but like you said it's prob just because I hadn't been looking although after a quick google and couldn't see any so it's looking like it's a less common bubble type
