Stereoscope ‘Cosmorama’ on Stand

The Cos­mora­ma is a large box-type stere­o­scope, most often seen mount­ed on a stand. The design was reg­is­tered on 15 Sep­tem­ber 1854, rather than patent­ed. The reg­is­tra­tion pri­mar­i­ly describes the use of two lens­es cut from a sin­gle larg­er lens. The most dis­tinc­tive fea­ture of the Cos­mora­ma is its curved front pan­el with Goth­ic-style win­dows sur­round­ing the lens­es. The view­er could have a hinged lid at the top, the rear, or both.
