What Does This Expression Mean?
This idiom describes a person, company, product, or organisation that is known for only one skill, talent, or speciality.

Origin and History
The expression originally referred to travelling performers.
In old fairs and travelling shows, entertainers often performed several different acts to keep audiences interested. However, some performers had only one trick that attracted attention.
Since they could do only one impressive act, people began using this description for anyone with just a single notable ability.
Over time, the phrase became part of everyday English and is now commonly used in business, sports, education, entertainment, and daily conversations.
