“La portlait de Mademoiselle Josephine”

Should really be:
“Le portrait de Mademoiselle Josephine”

Which transliterates to:
“The Portrait Of Miss Josephine”

Better said as:

• “Miss Josephine’s Portrait” or maybe
• “A Portrait Of Miss Josephine”

So... It's Flench? :D

Eh yup. Flench sounds about right.
