This image, on posters and T-shirts, is no longer as fashionable as it once was. It is nevertheless astonishing that a scheming, murderous tyrant - not even handsome in real life - adorned student walls and chests for so long. He even ousted Lord Palmerston from a London pub. And according to Charles Moore he has been displacing bankers:

In a recent conversation with Mervyn King, the Governor of the Bank of England, our talk turned to great central bankers of history. Mr King reminded me that the best known, though probably the least suitable, was Che Guevara, who was President of the National Bank of Cuba while maintaining his rank as a general. The famous picture of Guevara in his beret was taken when he worked for the Old Lady of Avenida Libertad o Muerte (or whatever they call it in Havana). It shows the natural bad taste of the human race that we scorned the dozens of distinguished central bankers whom we could have put on T-shirts and chose the one who was a financial incompetent (he declared that he wanted to do away with ‘material incentives’ altogether) and a murderer. In a rightly ordered society, young people would queue to buy T-shirts of the admirable Mr King smiling benignly through his thick gold-rimmed spectacles. 

Accountants, as we know, are even more boring than bankers. They look at your shoes when they talk to you, which, to be fair, is one up on actuaries who look at their own. Here's an idea - why not print T-shirts with pictures of incomplete ledger accounts and the challenging slogan: "Have you got the debit for my credit?" Thus accountants can mix business with pleasure and get down to some serious double entry.

As for that troublesome, lonesome creature the dangling debit, this could adorn a pair of underpants, negating any reserve and creating much goodwill.
