From the website:
See also our large and beautiful collections of art, female beauty, mythology and very decorative stocks. Although some 3000 different stocks are listed on this site, I also have more than 3000 stocks as yet unpublished here, due to a lack of time.As these are sorted by country and on alphabet, you can always inquire if I have any particular stock available. I would also be glad to help you find a suitable stock or company letter as a gift for your friends, relatives or business relations: any topic and any price range. Just ask !
