The ivory plaque identifies the retailer as "Robinson, 55 Grafton St., Dublin". Two features make this particular Cosmorama very unusual, the round lenses and the rack & pinion focusing knobs on either side of the viewer. Neither of these features appear on earlier Cosmoramas, I assume this is what is meant by "Improved" on the ivory label. Refer Wing, page 26/27 for more information on the Cosmorama.
