MattI'll clarify - in my experience, SGC has been reluctant to add anything additional to a flip, unless it is a well established hobby reality. I wouldn't expect them to blaze the trail here with this stamp, even if it is legit. Therefore, the lack of acknowledgment on the flip doesn't sway the argument one way or the other, other then to say this isn't a well known and documented stamp, which we already knew.
