This 2010 Christmas mailing consists of a greeting card, an Advent calendar and a small book. The symbols used on all three media represent Christmas customs from different countries. Since Stratley is one of the top management consultancies for the chemical industry, countries that are significant chemical locations were chosen. The book juxtaposes these symbols with the corresponding regional customs. The concept creates a numerical connection: 24 chemical locations, 24 Christmas customs and 24 days until Christmas.
