Rosenberg Publishing specialises in niche markets.
The company published the Comeng history series.
I was at the launching of the first volume, and was very impressed by the company's method of operation, attention to detail, and customer relations. There was a representative present, and I recall some sort of hospitality gesture: perhaps a cake or some wine?
That launching was held at STM, with a backdrop of a Comeng tram and a Comeng bus. There must be photos in the archive.
