Mailbox Letters Two JNL Font Family was designed by Jeff Levine and published by Jeff Levine. Mailbox Letters Two JNL contains 1 styles and family package options. Mailbox Letters Two JNL is the second typeface from Jeff Levine inspired by metal lettering used on mailboxes and homes. Each cast letter or number sat on a lower “rail” which was then slipped into a slot that held them firmly in place. Jeff’s Inventory JNL looked close enough to the original type style to use as a model for this font, and for typographic purposes there are certain punctuation and other glyphs that “float” above the rail. Limited character set.
