Q: I inherited a picture of a horse named Greyhound, a world champion trotter. It says it is “an exact reproduction of the original by R.H. Palenske reproduced in talio-crome.” My father-in-law bought it at the Par Soap Co. in Oakland, Calif., in the 1930s. Can you tell us what talio-crome is?

A: Talio-crome is a printing process that uses red, green and blue to make all colors. “Talio” is derived from the word “intaglio,” the process of etching a design on a plate. Reinhold H. Palenske (1884-1954) was an artist born in Chicago. Greyhound was a famous horse, a trotter who set his first world record in 1935 when he ran from last place to first to win the Hambletonian in Goshen, N.Y. By the time he retired in 1941, Greyhound held 15 world records. The Harness Racing Hall of Fame called him the “Trotter of the Century.”
