The London Bombings
There have been a lot of flag related responses to the London bombings. An example is the following from the July 5th edition of the Richmond Times-Dispatch:
The British Union Flag is shown here upside-down, I suspect unintentionally.
I have also noticed a revival of the so-called Grand Union Flag, the original flag of the United States (1 January 1776 until 14 July 1777), as a sort of Anglo-American solidarity flag. The Grand Union Flag, whether coincidentally or by design, was nearly identical in design to the flag of the Honourable East India Company as it existed in the 18th century.
My personal favourite as an Anglo-American solidarity flag is the 19th century version of the East India Company flag, with the British Union Flag canton in its current configuration.
