Sensory art, they called it. Where looking at the art evoked strong feelings in the viewer.
It was the newest sensation. Harry first saw it in Versailles, as they wandered past an art gallery. 'The latest art sensation sweeping the world!' He and Ron were there on an Auror assignment and had time to kill, so they went inside, hoping to see some of Dean Thomas' newest work. They stared at the simple portrait of a pair of clasped hands. Harry didn't know why, but he immediately thought of Mr and Mrs Weasley, wondering how they were.
Not being art conisseurs, Harry and Ron gave it no more thought, or so Harry thought. They completed their assignment and returned to England. But in Europe, the unknown artist was becoming a sensation. The fact that the artist wasn't selling – yet – made the art even more desirable.
Harry's eye caught an article, when he was desperate for any news from Paris. It was eighteen months later, and the unknown artist had gifted another painting to a gallery. Titled 'Home', it was a painting from inside the house, peering out the front door to the wide open spaces.
Harry would have sworn it was the Burrow. He saw where Bill and Fleur had their wedding, where he had had countless dinners outside in summer. If he looked hard enough, he was sure he could see the path down to the pond.
Again, there was no mention of the artist, but Harry instructed his lawyer to lodge an interest in buying the painting, to gift to the elder Weasleys. But his lawyer came back and told him that, once again, the artist wasn't selling.
A year later and the artist had a change of mind. The first painting sold for a huge price and the second tripled the first. The artist was in demand, but the company working for he or she could offer no promise of future work, and definitely wasn't releasing their name.
Harry put the art to the back of his mind. Ocassionally, when he was at the Burrow and looked out the door, he thought of that artwork and wished he had managed to buy it.
Little did he know how important that seeing that first artwork would be.
That it would bring Ginny back to him, albeit indirectly.
