Can someone confirm if this is Fred Trueman’s signature

I borrowed the book 'The Freddie Trueman Story' from a library in Eswatini (Swaziland) it was donated to the library in 1964 and has only been borrowed once prior to me. On the opening pages, there is seemingly Fred's signature, however I can not find an image of him signing in this manner, and it seems strange for him to sign a book in Swaziland. I hope someone can help identify any history to this book as it seems a waste to be sat unnoticed in a library for 60 years.
