Years ago, I obtained a Playbill that was purportedly signed by all six members of Monty Python, along with their collaborators Carol Cleveland and Neil Innes. The seller said that he originally obtained them outside the theatre after the show. I'm curious as to whether or not they're authentic. Most of the signatures have faded, but hopefully they're still legible enough to verify.

Also, about a decade ago, I wrote to John Cleese and Terry Jones, and received signed photos back. Since I'm asking about Monty Python, I thought I'd ask about those as well. When I was younger, I had a lot of trust in TTM signatures, but now I'm thinking that a huge amount of them must be secretarial.

Thanks so much for your help!
