Acknowledgements

I am very grateful to the following colleagues who generously offered their support and expertise to make this exhibit happen. Anne Cong-Huyen and Kristine Greive provided me with their technical support and feedback; Randal Stegmeyer and Karl Longstreth produced many of the high-resolution images. Moreover, I want to thank the U of M faculty and students who throughout all these years have help me identify extraordinary marks hidden in the pages of our manuscripts and early printed books.
