Pullman Facts No. 3 described the stupendous extent of Pullman operations that used 9,700 Pullman cars to house 64,000 guests per night on average. To supply these people, Pullman maintained a stock of 4.2 million towels, 2.7 million sheets, and nearly half a million blankets and pillows at more than 100 supply depots across the country. These numbers are all presumably from 1929.
Unfortunately, I don’t have a copy of Pullman Facts No. 4, but from the cover below it sounds like it covers an interesting topic: the construction of a Pullman car. Naturally, if I find one, I’ll post it here.
