Imperial and Royal Warrant of Appointment

 
An Imperial and Royal Warrant of Appointment during the Austro-Hungarian Empire was issued to vendors who supplied goods or services to the Austrian imperial court in Vienna and/or the Hungarian royal court in Budapest. The warrant was normally an official document, which enabled the supplier to advertise the fact and thus lend itself prestige. 
Suppliers continued to charge for their goods and services. The application process took years and was given only to those deemed of the highest quality to be worth to receive the honour upon personal approval of the monarch. The warrant was typically advertised on company letter-heads and products by displaying the coat of arms or the heraldic badge of the imperial eagle. Underneath the coat of arms would usually appear the phrase "k.u.k. Hoflieferant", which translates into English as "Purveyor to the Imperial and Royal Court". Depending on where the supplier was located within the dual monarchy, it could be adapted into the local language such as ""Ces. i Król. dostawca Dworu" in Polish, "C. a k. dvorní dodavatel" in Czech, or "Fornitore di corte imperiale e reale" in Italian.
The warrant was initially given to the owners of a company or a tradeperson, not the company itself. Only later were entire companies given the warrant. 
The warrant was given as a supplier for the overall court. However personal suppliers to the emperor or the empress were given a higher warrant as "k.u.k. Kammerlieferant"", which translates as "Purveyor to the Imperial and Royal Chamber". It was possible for a supplier to receive both warrant forms for exceptional quality of services and goods.
