This document consists of three pages. The first page features a computer-generated diagram of a snowflake-like chemical structure, presented in pink lines on a light background. The second page provides a printed explanation of this visual element, identifying it as the crystal structure of their first spherand. It states that the compound was specifically designed to bind Li+ and Na+ cations while rejecting all others, confirming its success. The third page is a handwritten letter from Don Cram to Professor Wiesel. In the letter, Cram expresses gratitude for a telegram of congratulations and an invitation to a meeting in Paris. He apologizes for his inability to attend, citing health reasons (recovering from shingles), and concludes by wishing Professor Wiesel a fine meeting and a happy 1988.
