Kay revealed the poster - based on the famous album cover - on appeal night
A charity poster which recreates the Beatles' Sergeant Pepper's Lonely Hearts Club Band album cover is due to go on sale in aid of Children in Need.
Supermarket Asda responded to pleas by comedian Peter Kay to sell the poster, which sees iconic 20th century figures replaced with children's characters.
The poster accompanies Kay's Animated All Star Band single, widely tipped to top the charts this weekend.
"It can only generate more money for a very worthy cause," said Kay.
The single - a medley of well-known pop songs - features characters including Paddington Bear, Andy Pandy, Pingu and the Teletubbies, alongside Kay's animated alter ego, Big Chris, from the Roary the Racing Car series.
Other celebrities taking part in the single include Neil Morrissey as Bob The Builder, Bernard Cribbins as The Wombles and the Beatles' Ringo Starr as Thomas the Tank Engine.
The download went straight to the top of the iTunes video chart after being released at the weekend.
All proceeds from the sale of the poster, also available online, will go towards the BBC's 30th annual appeal which has so far raised more than £20m.
"It's fantastic news that the BBC Children in Need poster is going to be available to buy - the requests and demand for it so far has been extraordinary," said Kay.
