Two flags and proposals for Slovenia were presented with his paper Two Flags, Two Proposals: a New System of National and Rank Flags of Slovenia. Typically one flag is proposed to replace an existing flag, but Zizmund presented two flags for Slovenia. The need for a new flag has arisen since the Slovenian flag looks like the Slovak and Russian flags.
In addition to the new designs, applications for the military and rank flags were proposed in succession to the newly proposed flags.
Could we be looking at the future flag of Slovenia? Only time will tell.
