Over a year ago, Adidas blocked personalisation of German football team shirts with the number 44 following controversy caused by the design of the number; it bore a resemblance to an SS Nazi symbol - the lightning-bolts symbol.
The DFB German football federation explained at the time that the design had been submitted to UEFA and that "no parties" had seen any proximity to Nazi symbolism. Nevertheless, an alternative design for the number four would be developed.
In Germany, glorification of Nazis symbols is totally prohibited. In Spain, the law of democratic memory bans glorification of the Franco regime but doesn't extend to, for instance, Nazi Germany symbols. In Playa de Palma, illegal street sellers are offering German football team shirts with the 44 number. The shirts bear the name 'Führer', and there are others with the number 88, a code for Heil Hitler; in Italy this number is banned from being on t-shirts.
The shirts, which are fake, are on sale for between 25 and 30 euros, but haggling can bring the price down to 20. Regular souvenir shops don't sell these shirts.
There isn't apparently much evidence of people wearing these shirts. A reason for this may well be that local bars are refusing entrance to anyone wearing them.
