Postcard with a theme #1

This swap is for anyone who likes a bit of a surprise when receiving a postcard. I would like to make this a series of swaps. The postcard will be sender's choice as long as it fits the chosen theme.

For this swap the theme will be : Metal structure

The theme can be interpreted any way the sender wishes but if you think it could be necessary , then put a brief explanation on the back. The postcard will be sent naked and can be a photograph or illustration. No homemade, free or ad cards, please. As it is sender's choice it can be prepared in advance of partners being assigned. On the back write one interesting fact to match the picture on the front. Something that you did not know or something you think your partner does not know.

I am not going to set a rating as I do not expect any problems within the group.

Please rate promptly. Give a 5 rating if you receive a postcard showing a picture that fits the theme and a fact on the back. A heart is for you to decide.
