Vintage chocolate and confectionary boxes and tins
Boxes of chocolate were a romantic gift for most of the twentieth century. The earliest example of a brand we recognise today is Milk Tray, which Cadbury's launched in 1916 .
By 1928 Cadbury's range included :
- King George
- Lady Betty
- Prince of Wales
You could always buy an unbranded fancy box of chocolates from a shop. Army & Navy stores sold a range which started at 5 shillings for a 1 lb box. But several other well-known brands started in the 1930s.
- Terry's All Gold - 1932
- Rowntree's Dairy Box - 1936
- Mackintosh Quality Street - 1936
- Cadbury's Roses - 1937 
A box of chocolates was a more significant gift than it is today. In working class communities if a boy gave a girl a box of chocolates, it was almost a marriage proposal.
A box of Milk Tray was cheap, in 1930 a 1/4 lb box cost 7½d (or about £1.40 in today's money).
'Black Magic' was more upmarket. The adverts told a story which emphasised the romance of giving chocolates. The company asked 7000 people for their opinion on the best flavours. The packaging was a simple Art Deco design. In 1933 a 'Black Magic' 1lb box cost 2/10 (or a whopping £7 in today's money).
Chocolates remained a popular gift especially at Christmas and the list of brands grew.
In 1965 Dr M Miller, a Labour MP, gave us an insight into the most popular brands. He complained that they were ripping customers off with fancy Christmas boxes. He cited Nestlé's Home Made assortment, Cadbury's Milk Tray, Terry's All Gold, Rowntree's Black Magic and Rowntree's Dairy Box as examples.

(*) 7/6 = 7 shillngs and 6 pence, see Old money for more details.
A reasonable number of vintage chocolate boxes have survived. People often used them to store buttons or other nick nacks. A few turn up on eBay in reasonable condition.
Chocolate boxes do not attract much interest from collectors. So you should be able to get most of the well-known brands for under £10. Look out for unusual designs and images particularly reminiscent of their era. In the 1950s ballerinas or kittens were popular motifs.
Of course with any collectable, condition is everything. Look for good quality boxes free from damage. They should appreciate in value.
