The international tour of al-Hariri's artwork featured two exhibition collections, The Spiritual Edifices of Islam historic mosques collection, and the Wahbi al-Hariri Artist Retrospective collection of 30 original oil, watercolor, and graphite pieces that form a broad retrospective of the artist's work. The retrospective collection spans a sixty-year period (1930s-1990s) and includes a special selection of works that al-Hariri completed in Canada, Egypt, France, Greece, Italy, Lebanon, Saudi Arabia, Syria, the United Arab Emirates, and the United States.
