I too love these photos and would like to use a couple in an article I am writing about the park. I can't offer any money, but will certainly credit you with the pictures when the article is published.
Dear Dragan,
I have to say that I like our photos very much. I prepared a text about Kroller-Muller museum for Slovak periodical with name "LÃnia" and I would like to ask you if is it possible to use some of your photos.
