The set of four multi-coloured stamps in the denominations of Rs 2, 5, 6.5 and 10 were issued on December 30, 1991, depicting yoga postures - Bhujangasana, Dhanurasana, Ushtrasana and Utthita Trikonasana - respectively.
"That was a time when yoga was not popular among the masses and Swami Ramdev had not emerged on the horizon. The India Security Press at Nasik printed 10 lakh pieces each of these four stamps showing perfect postures. They were meant to take yoga to people through letters and there was no brouhaha over it anywhere in the country," said N K Agrawal, philately expert and life member of Philatelic Congress of India.
"The stamps were circulated and then disappeared. Yoga was not replicated on stamps in India after that. This particular set of four stamps now fetch around Rs 500 in the market," Agrawal said.
Philatelic expert and member of World Association for Philately, Pradip Jain, however, said that the Department of Posts issued a stamp in 2009 on Maharshi Patanjali, revered for his book 'Yogsutra' (a compilation of aphorisms on yoga practice).
