Black handbag- no idea if authentic designer!

Thrifted this black handbag that looks an awful lot like a major designer. Have absolutely no idea if it’s real or not but the Gs are real age and it looks real enough to me! Anyway, your guess is as good as mine if this is real! Has silver hardware. Have only worn it once or twice so it’s in good condition. No rips in or wear on the fabric or leather. Smoke free pet free home.
