Not sure I like that big purple flower. Looks a bit threatening, like a spider in the middle reaching out!!!
I believe purple is a favourite colour of feminists but in many parts of Europe it is a sign of penitence! Also a flower might not appeal to everyone. A tree or tufts of green grass or a field of golden corn mabye.
The mnemonic RENTALS maybe has wrong image! How about ANTLERS?
The card idea (or as a fridge magnet) is excellent and Patrick has great ideas. I think this is an idea we should build on.
