In the beginning, the catalogs were made with extensive handwork. All of the models were drawn in color using the so-called tempera painting technique, they were cut out, and then they were glued in place on the catalog page.

The first Märklin catalog was printed in 1895 in which the items were shown as copperplate etchings. The text was printed in a black/white letterpress process. In a three-language edition, the firm was now able to provide catalogs to all of the German, French, and English-speaking dealers.

From 1921 on numbered consumer catalogs appeared regularly until the war years of 1941 to 1946. The title pages were already being printed in color then. Starting in 1929 the inside pages were also done in color, the first catalog to be printed completely in color being no. 12 in 1935.

In 1947, there was an issue exclusively for the dealers since paper was still in short supply due to the war years.

In July of 1948 and in March of 1949 there were also only supplements to the issue from 1947. The first consumer catalog did not come out after the war years until 1949 in a single-color version. A complete catalog in color did not come out until 1953 using a rotogravure printing process.

An interesting issue of the catalog with a copper metallic cover was printed for the hundredth anniversary in 1959. Other interesting catalogs came out in 1984, for 125 years of Märklin, and in 1985, for 50 years of H0 Gauge.

Between 1984 and 1990, separate catalogs were available for the individual gauges. Full line catalogs with several gauges came out in 1991.
