The liebig extract of meat company has edited since 1867 many ephemera and more than 10.000 trade cards sets in many languages. All these ephemera lithographic chromos are real antiques and more than 100 years old.  All chromo’s series are photographed and are available on this site. And practically all cards can be ordered.  Each set has many variations in verso and reverse depending on those country-languages.  Also examples of albums, menu cards, table cards, calendars and cook books have been listed in the catalogue   Many collectors do collect and invest in these to antiques related antiquarian ephemara. The domain is so big that it is both very interesting & intelectual to invest and learn at the same time : printing techniques, historiacl value, and not forget the educational and artistical worth. Chromos indeed are lithographic artwork, not yet appreciated and therefor far under-estimated by many institutional investors. We sell not only the cards which generations of collectors are looking for more than 100 years. My core business is selling full collections when arriving directly to interested investors. Buying one in an overall good condition is a good investment AND it is outstanding to have such a nice collection in your library at home or in your office. The liebig's collection and all other company's-collections have a full potential growth since 50 years of 10% each year, average for the common sets before 1900, but 20 à 30% average for rare sets and individual rare cards. It is a misunderstanding to collect those cards one by one because there will be so much lost time involved by seaching and a lot of frustration by not finding!
