Contact for Source of Segelflug-Bildkalender

Hi,

I am interested in contacting the manufacturer of the "Segelflug
Bildkalendar". I have owned them in the past. They are very nice large
format photo calendars. It is different from the (also very nice) soaring
photo calendars from Claus Dieter Zink.

I am interested in selling them to my customers but I can't find an contact
information when I Google Segelflug-Bildkalender.

If you own one of the calendars, or can help me, please let me know.

Best Regards,

Paul Remde
