While abroad, especially when on a mission like the Olympic one to London last weekend, I am always excited when I spot "This is Belgium" material. But honestly, it's not always as easy or obvious as you might think. I did not see anything that could link the National Portrait Gallery to this blog (but I like the reflection photo through the glass ceiling of the cafeteria) nor could I link St Paul's cathedral to Belgium (but I like the 'Thank you for visiting..." sign).
I thoroughly enjoyed Damien Hirst's expo and did find these black yellow and red shawls ready for me to be snapped in Tate Modern's gift shop ;-)
