What Dayacom authorized
Christopher McDonald wrote to Dayacom requesting permission to preserve pen-kit information and publish Dayacom product photographs and documentation with attribution. Dayacom replied through Sabina Hsu, Senior Secretary, on August 19, 2026.
“will allow you to refer our pen kit’s designs and modify it if possible.”
The reply was made in direct response to the preservation and photo-use request. Christopher McDonald has confirmed it as the usage grant for this Turner’s Atlas archive.
