There is so much right about it and only a few things that concern me, like the lack of flow to the downstroke of the T; the hard corner start to the hump of the H; the slow flow in the NN.
I think it's probably real though because most of the rest is so right.
I think this is the real deal. I've seen better Lennons that are no brainer and legit in my opinion, like how Lennon signed on both The Beatles signed Fan Club postcard and The Lennon/Harrison combo Diary one posted in this Beatles Forum.
If you want a tome on our credentials, please be patient: it'll take years to document.
Most of us have decades of studying Beatles signatures, both the group and solo. It's a passion born out our love and respect for the band, along with the hope of one day stumbling over a genuine set (!?!). This allows us to contribute - and I'm forever grateful to Steve for providing the forum.
This is a signed copy of "In His Own Write"...signed in April 1964...nice one!!!
