59828 Ossikar           Discovered 1999 Sept. 5 by G. Lehmann at Volkssternwarte Drebach.
The cartoon-figure "Ossikar" was created by German caricaturist Manfred Sondermann, father-in-law of the discoverer. Ossikar, the main hero of many caricatures with everyday-life humor, appeared in numerous magazines during 1991-2006 and in a book in 1993.
