I always thought it was “Waldo”, but perhaps Nick Dutt at Tattooz R Us in Kilsyth. Victoria, Australia is looking to avoid a trademark lawsuit?
Actually, the truth is that in Australia (and most places other than the US and Canada), the character is “Wally”, and was renamed “Waldo” in 1987 for the US market. I’m not really sure why. They also call him “Walter” in Germany (I guess even German children appreciate the value of being formal and polite), and “Charlie” in France (who knows why).
