Sefton local authority erected A3 chewing gum boards for people to stick their used gum and huge banners warning people not to risk hefty fines.
Beer mats were also handed out to businesses to spread the message.
Councillor Paulette Lappin, Sefton Council’s cabinet member for regulation and compliance said: "We are doing all we can to raise awareness of this issue and we continue to spread the message far and wide, nobody can have an excuse to drop gum.
“Dropping gum, like any form of litter, is a disgusting and unsightly thing to do and you can be fined so we are making sure there is no reason to do it.”
Further Gumbelievable events will be announced in the coming weeks.
