I vaguely remember to have seen years ago a Tichy with a
logo/trademark on it but I do not know anymore form/text/signature. You have 2 possible routes for clarification.
1. Contact the Prague proofhouse , they may have an answer.
2. In an Internet forum -possibly Czech origin - there
appeared a man who told that Gustay Tichy is his grandfather.
I understood he is living in US. With google you may be lucky to locate him.
All the best
