Lady Dax 1975

Hi all
I wonder if any of you can give me some advice...
I am about to list my 1975 Lady Dax on Ebay . It's a bit tired, but has all its original features, including documentation and flowered seat cover.
What sort of info should I put in the listing and are there any particular bits of the bike I should definitely photograph?
Thanks.

The more pictures the better, and don't forget the top and bottom of the seat.

I would never have thought of the bottom of the seat. Thanks for the tip.
