#1, Parizska, Josefov, Prague
It is very easy to get lost in Prague. It's even easier when you're more interested in looking at walls than at a map. You're only there a week, you'll never figure it out, so why bother over the coordinates? You can always look at a map later. This is one of the earliest numbers of my project, gathered as part of a 3-city, 2-week scavenger hunt across Prague, Vienna, and Budapest.
I've gathered thousands of images since the mad dash of 2006, but I still love this tiny #1. The scale is hard to judge from the picture, but it was hardly the size of a silver dollar. It, and the charming red line of pipe, was an underdog amid the maze of ancient streets and dizzyingly beautiful streetscapes. I remember distinctly the goblet of Delirium Tremens, mussels and frites consumed at the nearby Les Moules afterward as, mid-afternoon, it started to rain.
