Chéret was also called the "father of the women's liberation" during his lifetime because of his works - and not just bicycle posters. (When you live in Scandinavia - in a region with excellent levels of gender equality - you don't bat an eyelash at the idea of women's lib having a father). Much has been written about the bicycle's role in women's liberation (although never enough has been written) and there are many inspiring quotes about it.

What Chéret did was portray women in a new, refreshing and radical way. What contemporary society in Paris saw upon viewing the posters was women who were happy, care-free, stylish and lively.

 It heralded an age in Paris where women could openly participate in activities like wearing low-cut dresses and smoking. The female caricatures even became known as Cherettes. It all went hand in hand with the liberating effect that bicycles were having on all aspects of society.
