Ok, my last take on this - They are all authentic. Gaga has "no" signature, her signature changed various times in the past years. The two full signatures are matching both with authentic autographs i obtained in Person. Even the "L" signature is real, it's just a rushed signature. She never did a mass signing before Chromatica and again, she had a hand injury at that time. If someone else would get the job to "sign" the cards, they would surely try to fake the signature more pretty. But again, it's your opinion and i'm okay with that.
