The Directorate of Rubber Stamps disagreed, citing the Grand Frommaj's decree that Dunkrugerstan should be modern yet traditional, and the Director had decided that the "modern" part was of greater relevance. The Director demanded chromed steel lattices, polished to a mirror finish, and with 18/8 stainless steel bolts.
Both the Minister and Director were consulted by one of the Grand Frommaj's Trusted Advisors, who pointed out that the Taste Police Superintendent had separately required that all the billboards along the entire street should be of the same type. Yet the Minister of Paperclips and the Director of Rubber Stamps refused to meet with each other, or with the Trusted Advisor, or even with the Superintendent.
So the Trusted Advisor had his people design some of the billboards in chromed steel and obtained approval from the Directorate of Rubber Stamps. He designed the remainder in timber, and had these approved by the Ministry of Paperclips. Everybody was happy.
By the time the billboards were actually ordered, imported, and erected, the Trusted Advisor had long since departed from Dunkrugerstan. Which was just as well, for when the Superintendent of the Taste Police was justifiably appalled at the resulting unholy mishmash of styles, both the Minister and the Director each blamed the Trusted Advisor for failing to convince the other.
