Antov showcased the Bulgarian municipalities. Antov's paper was entitled Flags of Bulgarian Municipalities.
Antov pointed out that most Bulgarian flags are mono-coloured. It is also a Bulgarian law that chauvinistic symbols are forbidden. Unlike the USA, where local municipality flags are essentially unregulated by any kind of higher authority. It really is up to the people to select and design their own flag.
Since Bulgaria has been a EU member since 2007, a new push for new flags has swept the nation.
