A highway billboard using a saluting Adolf Hitler to advertise a Thai wax museum has been covered up after complaints from the Israeli and German ambassadors, the museum's manager said Sunday. “The idea came from a creative (advertising) agency, and we did not mean to cause any offense,” said Somporn Naksuetrong, the manager of the Louis Tussaud's Waxworks in the seaside resort town of Pattaya. The billboard, which in Thai language said, “Hitler is not dead,” had been up for several weeks on the main road from the capital Bangkok to Pattaya and was meant to promote the museum's planned opening next month. “We weren't showing his image to celebrate him,” Somporn said in a telephone interview. “We think he is an important historical figure, but in a horrible way.” Thailand has had past instances where icons of the genocidal German regime have been used for advertising and entertainment.
