Nice idea and picture Eve. I've made my 12 pics but I'm not sure I'm completely happy with some of them. Plenty of time to make changes though. I now think I want a front cover too 🙂 .
In just about every calendar I've bought over the last few decades, the Front cover is often repeated somewhere inside, but it's generally the back cover that gives you an example of what it will look like.
While that Pirelli calendar is not my exact cup of tea, it has given me an idea for a Henry Cavill one, so there might be a slight delay in uploading my image for February.
