Fossil art forms of nature manipulated on the computer. Starting point for these pictures are black and white photos of thin sections taken from fossils. The photos were scanned, colored and treated with different filters, but always in a manner that preserved the aesthetic form of the originals (corals and foraminifers). Calvendo calendars are premium products - a bit more pricey than others but with added benefits: Our calendars always look beautiful on your wall because we produce them locally with premium paper and sophisticated spiral binding, ensuring easy turning of pages and flat hanging against the wall. A protective transparent plastic cover sheet provides added stability and each calendar comes in five languages. Treat yourself to a Calvendo calendar and you get something that looks better all year round.
