Above, at least 6 different cover paper designs have been identified to date as having been used by Barnett. Most are what would be considered stock or "generic" patterned papers. These are standard gilt designs that were commonly available from printers and opticians, with some additional variation also provided by use of different coloured base papers. These papers were often purchased and used "as is", or could be ordered with additional custom printing added, such as Barnett's initials "JB". They were purchased and used by many slide makers, including both amateurs as well as professionals. The slide, 2nd from the left with initials "JA" was likely a "shop design" paper sold by J. Amadio. The firm of Smith & Beck offered a similar cover paper bearing their initials "SB" that is frequently seen on papered slides from the period. Although they are always unsigned (as far as is currently known), Barnett's handwriting on labels is quite distinctive and consistent, allowing fairly certain identification of his work. 

Barnett frequently used a common generic design that was further customized with his initials J.B.,  This design was printed in gilt, with 4 different paper colours currently known, as shown above. These initials were often covered over by a lower oval label or secondary retailer's label.
