Help Identifying Top Hallmark.

Is is a mark for a collaborcollaboration between Carolyn Pollack Relios and Vidal Aragon? I am having a difficult time finding the top picto-initial Hallmark. The only VA initial Hallmark if for Vidal Aragon. The piece is jumping. 925 SS Thunderbird with a Turquoise body and Coral tail that swings on jumpring.

I’m having difficulty finding the top hallmark, posting the entire piece might help. Carolyn Pollack collaborated with many artists, and has multiple collections.
