For this week's Sunday Challenge, for which the theme was anywhere you can receive or send mail.

Royal Mail painted more than 100 of its iconic and much-loved red post boxes gold to celebrate each and every gold medal won during the London 2012 Olympic Games and subsequent Paralympic Games.

The post boxes are to remain permanently gold to mark the achievements of the athletes and the historic Games. There's even a dedicated website which shows where the Gold Postboxes are to be found across the UK.

This particular one located in Ingleby Barwick was painted to celebrate Katherine Copeland winning gold in the women's lightweight double sculls. Kat Copeland, as she's more commonly known, had only been in the senior GB Rowing Team squad for two seasons when she and Sophie Hosking won their historical medal, the first Olympic title ever for the GB lightweight women’s squad.

The look of wide-eyed disbelief on Kat’s face at the end of the race has become one of the most memorable images of London 2012. And although after the Games Sophie Hosking retired and Kat herself took a break away from the sport she soon returned to competition and went on to win several major events with new partner Charlotte Taylor.

Sadly though they did not do well at the recent Rio Games where they were knocked out at the repechage stage. However, the look of sheer joy and disbelief on her face after winning gold in 2012 has forever earned her a place in the heart of the nation.

If you didn't see the race, or simply want to watch and enjoy Kat's reaction once again simply click here.

As for Kat's gold post box I've included an overall shot of it in the Notes for those who may never have seen one of them before.

Also, belatedly for Sight and Sound, what else but Spandau Ballet and Gold ...
