Ex 50p 'Canada Life' booklet dated August 1973 SG. DT12
S.G. Spec.: UB32 (5 x U87e)
Perf. type: P2s
Paper/gum: FCP(H)/PVAl Thin Paper
Phosphor: CB 4 mm Jet phosphor
DP14J
Jet phosphor is the result of the contamination of violet phosphor with green phosphor ink not intended for stamps. It glows a dirty yellow colour under short wave UV. Under long wave UV it gives a good reaction which is not found on normal 'B3' or 'violet' (1967-1993) stamps.
