In fear of sounding too persistent and annoying.
The gavroche was bought on therealreal.com, and as I do not know whether they employ an in-house HS authenticator, I'm a bit wary of their rock-solid knowledge of HS, to say the least.
However, I've been collecting HS since 1999 and had seen enough HS to know the difference.
I do know that Souvenirs de Paris came in one cw only and came as a part of Hermes Classiques collection for the PE-89. Whether it was ever issued as a gavroche I did not know, hence the question.
You say it was not... I believe you.
thus my question is... have you ever heard of super-fakes of older designs, never reissued? Let alone not popular and in a 45cm size?
And if it is a fake, it is a super-photo-fake (the print is impeccable, the silk is heavy, colors are bright, care tag looks real, copyright, H-P, artist's name - everything is there and doesn't raise a question). The only difference with a carre - there are fewer stars".
Heck, I won't send it back, it was cheap and even if it is a fake, I will keep it as a case in study.

I will even buy the carre, though I never liked it much, just to compare.
