Prince George“s first birthday will be marked with three official photographs taken last month.
One of the images will be revealed on Saturday while the remaining two will be released on the eve of his birthday.
The pictures were taken earlier this month when the little Prince visited the Sensational Butterflies exhibition at the Natural History Museum in London with his parents, the Duke and Duchess of Cambridge.
The photographs were taken by Press Association photographer John Stillwell.
Duchess Kate became Patron of the museum, which opened the outdoor butterfly house in April, in 2013.
The pictures will be a delight for royal fans around the world, who also watched as Prince George charmed the world in April on his first royal tour of Australia and New Zealand.
There the toddler showed a love for animals as he got up close and personal with those at Taronga Zoo, watching a bilby named after him, in honour of his birth, and eagerly clutching a cuddly bilby toy.
Prince George is just days away from his first birthday and he is already “charging around and opening doors”, according to his doting dad , Prince William.
The Duke of Cambridge shared the insight into family life at Apartment 1A in Kensington Palace as he chatted to crowds on a solo visit to Coventry”s War Memorial Park.
According to Gill Naylor, the Head teacher of Earlsdon Primary School, one of several schools who came to see William, the popular royal also joked: “I think George will be running faster than me very soon.”
Prince William also recently admitted that bathing Prince George is not the easiest of tasks.
The 32-year-old royal dad told guests at an event that tub time with the youngster – who turns one on 22 July – is a very tricky time of the day indeed for himself and his wife.
