Amitabh Bachchan recently signed on his original 1978 blockbuster 'Don' poster for Shah Rukh Khan when they got together at Dilip Kumar's residence to commemorate 100 years of Indian cinema.

The Great Gatsby star recently did a photoshoot for Filmfare magazine with actor Dilip Kumar and superstar Shah Rukh Khan for this momentous occasion.

"After the photoshoot with Yusuf Saheb (Dilip Kumar) and Shah Rukh is over, Shah Rukh asks me to sign the original poster of Don. I think the posters of old (films) are becoming very rare," Senior Bachchan posted on his blog.

"There are some still most favoured people that collect these memorabilia, and I am happy that they do. Posterity must know what the past was all about. Present without a past is incomplete," he added.

He also posted a picture of Dilip Kumar's house where he notice framed photograph of Pt Jawaharlal Nehru with Dilip Kumar shot at Nehru's residence, Teen Murti House.

`This picture stands in Dilip Saheb's room by his television and I put it up today because I was there when it was taken. He (Nehru) had invited a few of the film fraternity for tea around sometime in 1962.`

`I was there as an eager fan and starry eyed College student. Dilip Saheb, Raj Kappor and Dev Anand were there, and there is a photograph of a whole lot of us posing with Dev Saheb.`
