The gift shop at the museum, which opens tomorrow, will sell cuddly toy rescue dogs, fridge magnets, flags, and hoodies with the words ‘In Darkness We Shine Brightest’ written on them.

There will also be Twin Towers bookmarks on sale, and pear tree earrings that commemorate the pear tree that stood in the World Trade Centre plaza and survived the attack.

However, plenty of relatives are opposed to the gift shop’s souvenirs.

Diane Horning, who lost her son Matthew Horning on September 11, 2001, said that the idea was ‘crass’.

“To me, it’s the crassest, most insensitive thing to have a commercial enterprise at the place where my son died,” she said, as reported in Metro.

“I think it’s a money-making venture to support inflated salaries, and they’re willing to do it over my son’s dead body.”
