Persil washes whiter ... since always

Went to see the Museum of Brands, Packaging and Advertising in London yesterday. It is essentially a private collection of branded products, although a stunning one, spanning from Victorian age to today.
Interesting to see how many of today's brands were already around over 100 years ago (think Cadbury, Rimmel, ...). Also funny to see how some others haven't changed a whole lot in the past 60 years or so:


(Rolo, ww2 time. The pack hasn't changed a bit since then. Apologies for the poor picture quality)


(a 1950's Polo poster. It was already about mints and holes)


(a Persil pack from the early 50's, with a coupon! wow)
