“This piece of art seems so incongruous with everything, because you’ve got the history of the Berlin Wall, where you’re entering either the American or Russian sector. I just love that they decide to go with the Japanese sector instead. It’s completely out of place, and for that purpose I absolutely love it. Me with my Russian hat, being in Germany, looking at the Japanese sector. I just love how it all comes together.” – Andrew Allan

"I think this art stands out because it’s predominantly black, which the rest of them aren’t, the rest are trying to be very colourful. It’s remarkably different. The black is fitting, as the days of the Berlin Wall depict a very depressing atmosphere etc, [and] with Tokyo and New York it shows international influences in Berlin. All that combined, along with the depiction of the Berlin TV Tower and the big rotating Mercedes symbol, brings it all together quite nicely." – Andrew
