The advertisement was for Banker's Trust superannuation services and used 'A tan on us in Peru' an anagram of superannuation, as the header for their ad. There are other anagrams of superannuation....
I was intrigued by your 'Insights for Investors #11' in the Age Good Weekend this morning.
I was especially interested as I have long been a fan of that most famous of Mesopotamian stand-up comedians, Anu Garg. As you point out, Anu Garg (an anagram of 'an Ur gag', by the way) quite rightly said that "All the life's wisdom can be found in anagrams".
You hardly have to go past Banker's Trust itself to realise the truth carried in that statement.
Banker's Trust is after all an anagram of rank buttress. So apt in an industry governed by rank; attaining it and keeping it. But perhaps this is not the wisdom Mr Garg would have wished an anagram to show. Would 'snark tub rest' be better? Lewis Carroll contrived the Snark as large fearsome, creature prone to do nasty things to the innocent and the unwary. While I do not wish to deprive the snark of its relaxing soak I suggest that again this is not a truism that BT would like to advertise.
There is, of course, 'bark tent USSR'. I'm not sure what to make of this one but the USSR figures highly in BT anagrams. 'Tsar burst Ken', for example, bodes badly for Ken. Similarly 'Tsar sunk Bert' offers little better for Bert. For that matter, the advertisement refers to 'Truth #2: Investigation' - is it coincidence that investigation is an anagram of 'in giant Soviet'?
An investment company should avoid too much association with anything 'red'.
I fear 'Ask burst tern' would have the Gould League of Bird Lovers doing just that. If you find that distressing you would not get a great deal of comfort, physical or otherwise, from 'ten Turk's bras' or a 'bark net truss'.
You suggest that your heading, A TAN ON US IN PERU, is an anagram of 'Superannuation'. True but it could equally be an anagram of 'snout in a pea urn'. Or 'ruin on a sea punt'. Or 'a non-uterus pain' Or 'So a nun ain't pure?' Or some 35,700 other combinations.
You further quote Mr Garg as saying "Anagrams don't lie".
As a purveyor of ruin on a sea punt and a questioner of nun's purity, do you wish to reconsider?
Yours deranged and rearranged, J. Cosmo Newbery.
('Wormy Job Scene' and 'Womb screen joy'. Both true enough.)
Sadly, no answer.
