JAV-OCHA COFFEE
Back View - Example

So far, I only know of one text style on the backs of the few known Jav-Ocha cards, as shown below.  In at least one case, the text is overprinted on top of an existing illustration.

The text on the back of these cards indicates that there were 25 different picture cards "similar to this in quality". However, it's unclear whether the cards with this imprint are included in the 25 cards mentioned, or whether they're merely examples of the type of cards available. If the note that "no advertisement of any kind appears on them" really means that those cards were completely devoid of advertising on the back as well as the front, then it would probably be impossible to identify those 25 today.
