This unusual brochure came from Switzerland. The form number is OFS-9-57-X, with the X indicating it is an export brochure. This brochure contains a surprising amount of text. On the very last page of the brochure is a small image of another brochure, one I haven’t seen (see the very bottom image of this post).
This is the fully opened section of the brochure.
This is how the back looks fully opened.
This is the back when unopened.
This ‘Jeep’ Manual Para Flotilleros is a document I haven’t seen. It’s briefly mention on the back of the oil industry brochure.
