As a result of a thread I started elsewhere (under Authenticity Opinions) I have found out that I probably have the signatures of the above individuals. I believe they were signed on or around 26.12.71 - the date of an Ali fight at the Hallenstadion in Zurich, Switzerland.

There seem to be very few examples of their signatures on the internet. I found one Drew, one Alonzo and nothing for Dave. Does anyone have any examples they could post here or any details as to why Alonzo and Dave were in Zurich then (it is pretty clear why Drew was in town).

My examples, from a Zurich nightclub visitor's book, are posted below. There is an unidentified signature on each of the two pages but I presume these were local people who may have had little or no connection with the Ali fight or boxing in General (AG = limited company).
