In that era Dame Edna was never seen as gay, she was just a man who played the role of a women and got away with more double entendres than anyone would today. Some unenlightened Aussies would've taken years to realise that she wasnt really a woman.
Some of her more suble glasses were the same as my Grandmother wore and up until I was 8 or 9 every time I saw her on TV, I'd call her Nanna
That was TV in Australia in the 60's and 70's, nothing was crass or crude, but you could have a character making naughty comments that you had to think about and you could have a man dressed as a women without any kerfuffle. Plus after 8.30pm you could see Boobs and gay men/women kissing and touching each other.
I cant find the original ad that I've posted for POD, but Dame Edna did the full range of Malley's products at that time, its a pity that her roles died out with the end of Whirlpool over here in 1981.
We never had anything other than the 24" machines over here, by the end they were rated at about 6kg capacity which was competitive with everything else on the market at that time. I love the touch controls on those, they would've been totally unique on the Market here at that time.
