You really did find all hidden numbers – a fantastic job! Not many readers get to access this secret area. And because of that, I would like to get in touch with you in person and offer you a very special gift:
A personally signed (not printed / not digital – real pen on paper) poster! This will come at no cost to you and be sent to you via regular mail. Would you like that?
If so, please fill out this form (ask your parents or a guardian to help you) and I will get in touch shortly!
And again: Very well done!
All the best,
J. I. Wagner
PLEASE NOTE: In one edition of “Legacy of the Inventor”, the chapter 14 illustration was printed too dark. The secret number is barely visible. Just so you know – it is “3”.
