Quality Street was launched in 1936. The tin design showed two characters, Major Quality and Miss Sweetly, loosely based on Barrie’s Captain Brown and Miss Throssel.

When the advertising campaign made its debut on the front page of the Daily Mail on May 2, 1936, their parts were played by Tony and Iris Coles, the children of the campaign’s manager, Sydney.

It became a phenomenal success, partly due to the quality of the product, but also because Harold had cleverly found a way to bring the taste of chocolate to the masses.

1930s chocolate was still an expensive treat but when they added a small number of chocolate-based sweets with chocolate coated toffees and fruit creams, Mackintosh made Quality Street more affordable than a box of chocolates giving everyone the chance to taste the delicious sweets.

It had 18 different flavours in the original tin. The flavour that made the biggest immediate impact, though, was the caramel swirl, so much so that it became a product in its own right, packaged in a tube, named Rolo, and launched in 1937.

It is certainly a bit different now for sure.
