Trivia Advent Calendar

[Eva Elisabeth]

Happy Advent to all! Today is Dec.1 and in Germany time to put up and open the first window of the Advent calendar. So my idea was to also "put up" a trivia Advent calendar for the forum members. Before explaining the rules please allow me a short glimpse on the history of this custom which, AFAIK, is less common outside Germany, Austria, and Scandinavia.

The first Advent calendar was invented in 1851 to help the children count down and await the time until Xmas. The kids got 24 pictures, one day by day, to put up on the wall.

In 1903, the first printed Advent calendar, entitled "ln the Land of the Christ child" was produced:
   
It consisted of two sheets of paper - one with pictures to cut one out each day, and another one to complete by sticking them in.

In 1920, calendars with windows to open came up:
   
I grew up with the chocolate version, which you will find in every German home with kids (and not only there):
   
...despite the homemade one (and it's almost more fun to create than getting one as there are so many cool ideas):
               
The Scandinavian tradition is to burn down a marked bit of a candle each day:
   
Not only kids get Advent calendars! There's e.g. the beer version for the gentleman, or the cosmetics version for his spouse. And not to forget the dear pets:
   
Newspapers and magazines, on- and offline, launch Advent calendars, e.g. this free-download-software:

Finally, many German townhalls are now decorated as an Advent calendar, e.g. the Hünfeld townhall:
   

Now back to the trivia. I will open now a window to peep through at a well-known "Lincoln story" picture or item, and I hope you'll have fun trying to guess what is "behind" the window.

(Maybe my shedule won't allow to provide a new window each day - but you are welcome to add and post your ideas, too!)

Voilà, window #1:
   
Who/what is behind this window?
