Donald Duck comics by Don Rosa Easter Egg - Hidden D.U.C.K.

In almost all Donald Duck comics made by Don Rosa you can find the word D.U.C.K.
Most D.U.C.K.s are in the first picture.

D.U.C.K. stands for "Dedicated to Unca Carl From Keno". "Unca Carl" is the well known Disney writer Carl Barks. And "Keno" is Don Rosa (Keno Don Hugo Rosa).

Carl Barks was Don's favorite Disney artist and that's why Don is dedicating he's comics to Carl.
