Here's how the Leeds Play Bills homepage introduces the database:-
The Playbills site
The Leeds Playbills site is part of the Leodis digitisation project funded by the New Opportunities Fund.
What is available?
This site is making available all the playbills in the Local Studies Library collection from a wide range of Leeds Theatres such as The City Varieties, The Grand, The Princess and the Theatre Royal. The site provides a unique insight into theatre life in Leeds between 1781 and the 1990's. The site also contains some circus bills, such as those from Pablo Fanque's Circus.
