CD 106.1 (F) DUQUESNE. / G.CO. (R) DUQUESNE. / G.CO. in cornflower blue. A small triangular flake above the upper wire ridge (right side in photo) and a tiny nick above that. Purchased in 1986 at the London show from a well known collector (both then and now). $86 gets it to your door – cont. US, a little more if she has to travel further. PayPal, check OK. Thanks and best wishes, Bob
