Here is an interesting one. The story goes that a fan sent the Beatles Dan club quite an elaborately decorated letter. It came to the attention of Paul who typed a response letter and signed it. On the back it is signed by John, George and Ringo. The Paul signature is a classic early signature and I can’t tell if it’s stamped. The content on the letter that can be read is good. The Ringo looks good but John and George are questionable IMO. Any thoughts?
