I purchased an autograph book from auction and it has quite a few magicians inside including Robert Harbin, Peter Warlock, Francis Haxton, Jasper Maskelyne, Willane, Al Koran, Dante, Cecil Lyle , Geoffrey Buckingham and others.
This listing is for the Chavel, Dexter and Devano signatures.
The signatures back onto each other.
Harry Devano (1918-1996), born Harry Waldie Mitchell in Scotland.
Will Dexter (1906 - 1985) was a close-up worker, mentalist and writer.
Dick Chavel - I know nothing about him.
