1868-77 watercolour on native paper, the study illustrating a wide range of shades, comprising unused (10 with a reconstructed sheet in red and three in the orange shade), used (6, one cancelled in magenta, one in orange and an apparent double print in red) and used on covers (32 including orange, vermilion and carmine shades, some in combination with India and three bearing two examples). Condition quite naturally is variable though a fine lot for the specialist. S.G. 60-65. (48)
