Twinning: Seeing double - and in some cases treble - at sibling festival

Sets of twins and multiples posed for a group photo during the Twins Days Festival in Twinsburg, Ohio

They gathered together ahead of International Day of Twins – which is celebrated on Tuesday.

The Twins Days Festival is the world’s largest gathering of twins and multiples and celebrates its 42nd year.

It is held in honour identical twins Aaron and Moses Wilcox, who founded Twinsburg in 1817. Siblings were this year urged to wear costumes which celebrated where they or their families have come from or travelled to.
