In 1977, the 50-year-old Queen Elizabeth II of the United Kingdom had been on the throne for 25 years. Peaking on June 7th to tie to the Queen's Official Birthday, the anniversary year - the Silver Jubilee - saw street-parties and carnival parades across the country, 4,000 organised in London alone.
These photographs show one such event - a tractor-led street carnival in Cobham, Surrey.
