This is the Cartoons by Josh Calendar 2020 page. Although I do have a few copies left I am now selling the 2021 edition which you can buy here. If you want a copy for reference/posterity please do email me – josh ‘at’ cartoonsbyjosh.com
The 2020 edition was available with the book ‘All you need to know about Climate Change… in cartoons’ celebrating 10 years of cartooning since the Climategate. You can still buy the book, of course, and I have a few signed copies available too which you can order on the Book page. It is also available on Lulu for £14.99 and also on Amazon US and Amazon UK.
