An irreverent alternative logo for next year's World Aids Conference in Thailand, which features two elephants mating, has been criticised - because the male elephant is not wearing a condom.
No joking matter - how the official logo appears
The design, which has appeared on flags displayed by community groups taking part in the National Aids Conference in Bangkok this week, makes fun of the official symbol for next year's event, which features three elephants - male, female and a baby - standing side by side with their trunks upraised.
An official from Thailand's Diseases Control Department said the unofficial logo fails to convey any meaning, and sends the message that community workers are obsessed with sex.
He also said it was not educational because the elephants were having unprotected sex.
Elephants are revered in Thai culture as symbols of wisdom, strength and longevity.
