The history of airmail began in 1911 when the Frenchman Henri Pequet, then aged 23, transported by air a mail to India. On February 18, 1911 the first flight carrying official mail aboard a biplane Hommer-Sommer took place. It took place during the Exposition of the United Provinces in Allahabad, India and lasted 27 minutes. It carried about 6,000 letters and postcards to Naini railway station from where they were transported by railway. On October 15, 1913, the first official airmail flight took place in France.
On the stamp behind the portrait of Pequet, evocations of India (the tomb of Prince Khusrau and window) are transforming into folds and letters.
