Here is the catalog of Inujirushi (Dog Mark) bag in 1970s. Inujirushi was typical cycling bag in Japan. It had stopped production temporarily in early 90s.
Later a shop which was named "Inujirushi bag factory" was established at Asakusa Daito-ward Tokyo, has sold tote bag, shoulder bag, pouch, and so on. Although there were not so many kinds, canvas front bag and leather saddle bag which are made by build-to-order manufacture have been sold, too. However, present factory is not direct line of the former factory. It seemed to have bought the brand of Inujirushi.
This centerfold 4 pages catalog seemed to have been issued around early 1970s.

The catalog was offered by Mr. F. K.

This is the front page. The camping bicycle which was equipped with a front-side carrier, and the sportif bicicy which had the direct-attached center-pull brakes, were shown in the page as sample models.

Six kinds of front bag were introduced in this page. There must have been a number of cyclists who have used the rubber band type No.12 or No13 as a "TA type".

No.21 was a small front bag for sportif bicycle. The saddle bag was suitable for English club bicycle.

The front bag which could put in a thin Rinko bag to the bottom and the Rinko bag which could be used as a sleeping bag were novelties. The name and address of Hasegawa bicycle shop was stamped on the bottom right.
