Blossom
On Phoenician steles, you regularly find generic blossoms that don’t seem to depict any particular flower. They’re inconspicuous decoration. But later spooks seem to reference these blossom symbols as puns. It may be that to spooks, they represent the word לבלב lblb livlev for “bloom” & “blossom”, which is of course a Levi pun, and thus stands for “mockery” & “finance”. May also explain the name Blum.
