Oldest Logo still in existence and used.

 It is amazing to see that a company still uses and lives on with its 300 year old logo and brand icon.
Twinings is an English marketer of tea, based in Andover, Hampshire. The brand is owned by Associated British Foods. It holds the world's oldest continually-used company logo, and is London's longest-standing rate-payer, having occupied the same premises on the Strand since 1706.

The founder of Twinings was Thomas Twining. He opened Britain's first known tea room at No. 216 Strand, London, in 1706; it still operates today.^[2] The firm's logo, created in 1787, is the world's oldest in continuous use.^[3]

Twinings' shop on the Strand in central London. It was established as a tea room in 1706.

Holder of a royal warrant, Twinings has been owned by Associated British Foods since 1964.^[4] It sells a variety of regional and flavoured teas such as Lapsang Souchong, Lady Grey, and Darjeeling, as well as infusions, coffee, and hot chocolate. It is generally accepted that the company was the first to blend Earl Grey in Britain during the premiership of Charles, 2nd Earl Grey, although this is disputed^[5] by rival tea merchants Jacksons of Piccadilly,^[6] which is owned by Twinings.^{[clarification needed]}
In the mid-twentieth century, it made use of the advertising character Little Miss Barber.

Deviled ham and devil logo

Illustration of can of Underwood Deviled Ham, 1921 advertisement.

 

Deviled ham was created in 1868^[1] as a mixture of ground ham with seasonings; deviling would also be done with other meat and seafood products. This included turkey, lobster, chicken, and tongue. Deviling consists of adding such spices as hot sauce, cayenne pepper, Dijon mustard, or chopped chili peppers. Deviled eggs are one well-known example of this process. The devil logo was trademarked in 1870 and it is the oldest food trademark still in use in the United States.^[1] The red devil that debuted in 1895^[1] and started as a demonic figure evolved into a much friendlier version when compared to the original.
The older version, in use during the first half of the 20th century, can be seen in many old magazine advertisements, such as this advertisement from Woman's Home Companion, August 1921.^[21] It lacks the pitchfork and smile of the modern version, but has long fingernails not found in the modern version. The barbed tail is in the shape of the letter W, and along with the lower-case M to the right of the devil forms the abbreviation "Wm.", for William, as in William Underwood. The lettering in the logo and on the can are also spouting small flames, reinforcing the spicy devil concept. In 2008, B&G Foods updated the devil logo by adding color to the previously all-red image. The pitchfork became black, and small amounts of yellow were added in the tail and horns, along with shading to add depth.

The devil logo has appeared on Underwood products that are not deviled as part of the overall brand identity, such as sardines and chicken spread.^[1]
Other companies have made deviled ham products. In 1895, at least seven other companies produced their own versions of a deviled ham, among them Armour and Company, and in 1900 Libby's entered the market with its own deviled ham product.^[22]
In 1906, the Massachusetts Board of Health banned all deviled meats, except Underwood's, from sale in Massachusetts.^[23] The National Billposters' Association, based in Chicago, center of America's meat packing industry at the time, then banned its members from posting bills with devil images on them.^[24]
