What are the best methods for storing a 'frozen' condition comic book long-term?

Long-term storage for a 'frozen' comic involves several steps: First, use acid-free backing boards and Mylar bags. Second, encapsulate the bagged and boarded comic in a CGC or PGX case for protection. Third, store the encapsulated comic in a cool, dark, and dry environment with stable temperature and humidity (around 65-70°F and 45-55% humidity). Avoid direct sunlight and basements prone to flooding.
