When I traveled in Mexico many years ago, in the interior near Guadalajara, I stayed in an old fashioned hotel called the Hotel Francis. It had a stained glass skylight in the lobby, and the rooms were arranged on each floor around the central opening to the atrium. Old dark wood doors and trim, and a set of stairs but no elevator.
The room key came on a metal, enameled keychain with the name and address of the hotel on it. When I left I purchased a keychain like it, as a memento. I still have it.
This ornament reminds me of that hotel key fob, for a family hotel in Paris. It has the style and look of the 1930's, old fashioned with yellow and blue design and the key hanging alongside a handmade cast pewter Eiffel Tower charm.
I thought it might be fun to use on a keychain, with a faux Master key hanging as one of the dangles! Or swaying from a rear-view mirror, to dream of a trip to Paris or remember one from long ago.
In the spanish translation novel I've been reading lately the characters made a trip to Paris - maybe they stayed at this old family style hotel. It's a fun thing to think that they did.
