For 2019 I have currently three calendars for sale, all with a transparent cover sheet, format 42cmx21cm, thirteen pages in all:
London, focusing on Bridges over the Thames / £ 20
Verbier (for sale in the Verbier Tourist Office) / Sfr 25

You might be interested in offering these calendars as a corporate gift. Minimum order then is 10 calendars and I can add your logo on all the pages. Prices for size will be substantially lower from above.
