The commemorative sheet went on sale on Tuesday
The range of activities undertaken by Girl Guides - the UK's largest youth organisation for girls and young women - features on a new set of stamps.
The Royal Mail has issued them to commemorate 100 years of Girl Guides.
The movement's four age groups - Rainbows, Brownies, Guides and Seniors - each figure on their own stamp.
Their designs feature photographs of youngsters beside images depicting popular Guiding activities, such as baking, drawing, swimming and climbing.
Julietta Edgar, head of special stamps at the Royal Mail, said: "We wanted this special centenary miniature sheet of stamps to capture the many activities undertaken by Girlguides today.
"There are an estimated 2.5 million stamp collectors and gifters in the UK and many of these will have started their stamp collections when they were looking to achieve badges such as the 'collector' as a Brownie or a Guide."
The Royal Mail's Special Stamp Programme celebrates British life and marks events and anniversaries.
Last month, a set of stamps featuring classic album covers was released.
Other recent releases have included classic British designs - such as Concorde, the telephone kiosk and mini skirt - the bravery of firefighters and the 250th anniversary of the birth of poet Robert Burns.
Girlguiding is the UK's largest voluntary organisation for girls and young women, with about 550,000 members.
Famous former Guides include singer Pixie Lott, TV presenters Kate Silverton and Gaby Logan and Olympians Dame Kelly Holmes and Dame Tanni Grey-Thompson.
