Souvenirs to commemorate The Straits Times' 170th anniversary are proving popular among visitors to its ongoing multimedia exhibition, Singapore STories: Then. Now. Tomorrow.

More than 110,000 people have visited the exhibition at the ArtScience Museum since it opened to the public on July 17, and more than 500 copies of the book Front Page: STories Of Singapore Since 1845 have been sold.

The ArtScience Museum is the co-curator of the exhibition. The free exhibition, which also marks Singapore's Golden Jubilee, runs till Oct 4.

About 200 images were specially selected from the exhibition for the book, including reports, headlines and never-before-seen photographs from the English daily's extensive archives.

Sponsored by the Bank of Singapore, the book is on sale at $23 at the museum.

It takes readers through key events in the Business, World, Home, Sport and Life sections of the newspaper.

For Singapore Press Holdings chief executive officer Alan Chan, reading the original story on the 1986 Hotel New World collapse was "a walk down memory lane".

"As a young officer in the Ministry of Home Affairs in 1986, I was personally involved in the Hotel New World rescue operations.

"The article brought back vivid memories of what we went through," he said.

The general manager of Straits Times Press, Ms Susan Long, said shelves at the museum had to be restocked at least 10 times with the book.

Major bookstores here have also ordered 2,000 copies of the book, with Kinokuniya selling more than 200 copies so far. It has also been featured on the bookstore's bestsellers list for more than three weeks since July 20.

Also selling fast are the vintage notebooks, at $9 each. They feature scenes from Singapore's past on the cover, such as cheongsam-clad women in Chinatown and street hawkers. More than 400 notebooks have been sold at the museum.

Other collectibles on sale at the museum include The Straits Times print umbrellas, available in two colours, at $20 each.
