It is typically packaged in small bottles, with lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper.
The tape was placed into a second specially adapted Flexowriter which had two paper tape reading heads; one would read the text while the other controlled the spacing of the print. Spacing codes were stored in relays inside the machine as a line of text progressed.
The first of these to unambiguously depict the paper fortune teller is an 1876 German book for children. It appears again, with the salt cellar name, in several other publications in the 1880s and 1890s in New York and Europe.
