spot the balls

​Fundraising tickets normally ran as a private lottery in pubs and clubs 
Printed on tinted paper with black ink. 

Outside has room for the good cause name to be added by you and the other side has numbered spaces that are sold for a fixed price, normally £1 or £2,  once all the spaces are taken you can cut the thread on the sewn spot and open up to discover the wining number inside.  
All tickets are sewn closed for added security of the winning number.   
The prize is then given out and the remainder is given to the good cause. 
Prize size is a fine balancing act of raising enough money for the good cause and having enough of a prize to tempt people to part with their money.
