The signed index card in black Sharpie looks good to me. The second one you shared (with red background) looks fake. I've attached two Edge graphs for comparison. Both were obtained in-person in '97 during the Pop Mart Tour.
U2 was staying at the Ritz Carlton in Chicago. After show on Pearson Street- Bono and Edge signed, took pics and shared left over pizzas from the gig.
Generous, caring and unpretentious- one of the COOLEST bands EVER!
