Patented by Richard Smith for MS&J on April 15, 1879 [USPTO]. Later also known as Relievo. Cast by O.E. Lehmann as Umbra [Reichardt 2011]. Not to be confused with the earlier Relievo (1878) and Miller & Richard’s Relievo (c.1887).
The sample uses a modified ‘W’ for ‘V’ and might be inauthentic in this regard.
