Regel & Krug

Address: Leipzig, Kohlgartenstr. 57 (1895, 1898), then moved to Leipzig-Reudnitz, Comeniusstr. 13-15 (1907). In business from: Sept. 1, 1894 until 1931 / 1933. Regel & Krug was a member of the NBC Cartel.

There is a very good account of R&K on the TPA web site giving details of the various printing processes used.

Early cards spell out the company name. Around 1909 Regel and Krug produced a series of cards of the Romanian royal family, and on these cards they also added as logo a monogram of RK, see card 3741. Later still they used the semi-circle logo see card 4146. Probably as part of its drift (back) towards greetings cards, which TPA implicitly disapproves of, it later still issued illustrated cards in the "ERKAL" series. The example, printed in cheap half-tone, is one of a series illustrated by Luis Usabel, which has an LU logo in the stamp box. Luis Felipe Usabal y Hernández was a Spanish artist, 1876–1937.

Jean Ritsema has suggested that cards with this RK logo might also be products of Regel and Krug, based on the interleaved timing and numbering of the cards and the use of an RK monogram as logo, though the two monograms are not identical.

At this link there is a large collection of illustrations of Regel & Krug cards, with many of the subjects identified.
