Why don't they put pics of the stuff online?
Why don't people take a picture of their jacket/scarf/shoes/whatever they are wearing? I turned up with a picture of my missing jacket last year but they didn't have it. Some goon stole it from the Hofbräu tent.
no. 9 of "Ten Things to Observe at the Oktoberfest":
If you lose something, don’t panic! There is a special Lost and Found at the Oktoberfest grounds. If you bring a camera or other apparatus it’s a good idea to write down the model and possibly serial number. Such information makes relocating lost items much easier for the staff.
