Hey, what the hey! You'll have to look twice at this unusual typeface from Jeff Levine. Utilizing the sans serif lettering found in Trade Printer JNL, this novelty font combines two staggered outline versions that are blended together to give a double-image effect.
This works best at large point sizes and with minimum word count. Use it for attention-getting phrases such as "You'll See Double" or "You Won't Believe Your Eyes" (or similar ad copy).
