The Mysterious Omnibus

The splendid geometric pattern is Omnibus, named by Heacock and Bickenheuser. The pattern was introduced by United States Glass in 1911 as their #15124 pattern (below, left). Interestingly, the pattern also featured in their 1915 catalogue for Mexico and South America.

​We have been interested in this pattern since 1996, when a blue Carnival Glass Omnibus pitcher was found in the UK. A few years later we were intrigued to see, in a showcase at Renningers Antique Center (in Pennsylvania, USA), the water set that is pictured above, left. 

Unfortunately we couldn't get access to the display, and so we could not handle the items.

There were two very noticeable features - the shape of the pitcher and the colour. The pitcher at Renningers had a flat top and proportionally, a very small pouring lip. It was very different to the shape of the U.S. Glass Omnibus pitcher, which is also known in Carnival Glass. Additionally, the olive green was a colour which is not associated with Carnival made by U.S. Glass. 

We published this information in our “NetworK” journals (#12/1996 and #26/2000) and mentioned in our books “A Century of Carnival Glass” and “Magic & Mystery Second Edition”.

There is a conundrum. 

Many of the “finds” of Omnibus Carnival Glass pieces have been in South America, which begs the question of whether they were exported there (promoted in the US Glass 1915 Mexican-South American catalogue) or were they actually made there? 

The answer, based on current evidence, is likely to be “yes” to both questions. Some were exported and some were probably made there (possibly copied and extended by a South American maker). Research in ongoing ...

We have documented a number of other USA-South America connections, for example for Rising Sun and Imperial patterns, and no doubt there is more to be discovered about the connections between Carnival Glass production in these two continents.

Below is a Butler Brothers ad from February 1911. It shows the range of shapes in the Omnibus pattern that US Glass was making in crystal at that time. To date, the only shapes reported in Carnival Glass are the pitcher (with both shapes of top) and tumbler.
