John signatures from that period are tough. That said, I think it has good traits and is probably authentic. The Paul signed CD isn’t authentic in my opinion.
To be honest I don’t like either of them. Are Frank’s COAs legit? The McCartney COA is dated May 2024 - I would have thought that style of signature would have been questionable by then?
I’ve compared the 2 COAs in the OP to several I have from Frank and all my COAs are on crisp white paper stock with that vibrant blue (teal) highlight line under the heading. These John and Paul COAs look like copies to me.
