In the late 1850's, Oliver Wendell Holmes invented a handheld stereoscope, which really took off in America. Paper card stereo views were produced from the early 1850's until the 1930's. Through the years, stereo views were made in almost every medium known to photography. Millions of different views were created throughout the world during the Victorian era.
During the Victorian era, mourners sometimes collected their tears in gold decorated "tear bottles" to keep as a remembrance for the next of kin. It has also been said that the widows would go to the grave on the anniversary of the first year of death and sprinkle the tears on the grave to signify the end of the first year of mourning.
