A geometric sans much like Futura, but with joining strokes. Issued by Photo-Lettering as Thomac in four numbered weights (2, 4, 7, 10), without credits [PLINC One Liner 1971]. Listed in a 1978 feature on Ed Benguiat as one of his designs.

Nick Curtis credits the design to George Piscitelle [MyFonts] without providing a source for this info. His Kallilu NF explores a similar concept, albeit with different base glyphs.
