Figurines of former pro-Russian separatist commander Igor Strelkov from the collection entitled “Toy Soldiers of Novorossiya” are on display at a workshop in Moscow August 29, 2014. A Moscow-based maker of toy soldiers has sought inspiration for his creations from Ukrainian rebels fighting government troops in the east of Ukraine. Toy soldier maker, Timur Zamilov, displayed his new collection of rebel fighters cast in metal on Friday, before they are due to go on sale. His new collection is entitled “Toy Soldiers of Novorossiya” (New Russia), a reference to regions in eastern Ukraine where pro-Russian separatist fighters want full independence. Zamilov's selection includes models of Cossack soldiers, volunteers, soldiers bearing anti-aircraft missiles and even a miniature of prominent rebel leader Igor Strelkov.

A worker sweeps leaves below a historic spirit still at Suntory Holdings' Yamazaki Distillery in Shimamoto town, Osaka prefecture, near Kyoto, December 1, 2014.

Despite its unlikely birthplace, last month Yamazaki's Single Malt Sherry Cask 2013 trumped more than a thousand challengers to be named the world's best whisky by leading critic Jim Murray in his Whisky Bible 2015.

Hair stylist Marcelo Avatte (R) prepares to fit Isidora Serrano, a 14-year-old who lost her hair due to chemotherapy to treat her bone cancer, with a natural hair wig in the cancer ward of the Luis Calvo Mackenna Hospital in Santiago, October 23, 2014. The wigs, handmade by Italian-Chilean hair stylist Marcelo Avatte and his team, have helped the children regain their self-esteem and confidence during cancer treatment. Renowned for making customised wigs, Avatte has donated more than 300 wigs since 2009 and says he was motivated to begin the project by the pain he felt when his own son lost his hair during chemotherapy.
