Deciding on a more unusual theme to collect can come down to a very personal connection. I used to drive a Citroen 2CV for many years, so, when its day was done, I thought it would be nice to collect them on postcards.
Most of these are very much more decorative than mine. I would have loved to have one with sunflowers all over it. A fun design to match the fun of driving one.
This is always going to be a relatively small collection but I hope it's still growing. I have 15 - 20 now, but not one matches either of the two I used to own. The first was a plain yellow as seen in one of the James Bond films, and the second was a little more exciting: red with grey trims!
