You have to look quite carefully, but this is a set of cookie-cutter style statues of The Beatles in the St. Pauli quarter in Hamburg, where the band played regularly at the very start of their careers.
The fact they've gone for silhouettes is probably explained by the fact there are two plaques at the foot of the drummer - allowing it to represent both Ringo Starr and Pete Best. Also, some distance away, is fifth member Stuart Sutcliffe - but to get him in shot made the band even harder to spot! You'll have to Google to see a shot which captures them all.
