Victorian white glass buttons 1840’s to early 1900’s
On this card they are all opaque white buttons
Among glass buttons the term Victorian is used specifically for those of opaque (or more rarely, transparent) white or colored glass with conventional and floral designs molded in low relief or incised, with paint or luster trim. They typically have four-way or two way metal box shanks.
Pictures other than floral types are unusual. Many have designs of Art Nouveau influence
