Undocumented powder jar has the rose alpine decoration and metal lid as shown on the Miami Valley Study Group website mvsg.org devoted to Cambridge glass.
Mark Nye has a page in his Caprice book dedicated to these two powder jars. (Page 23) . "Probably the most controversial pieces of glass that are potentially from the Caprice line are two powder jars. The merits of these pieces have been argued ever since the first ones were found. Unfortunately, no Cambridge records have been found that would confirm the production of either piece as Cambridge open stock items or private mold work."
