My dad worked for a company served by the UPRR but had no intention of using that leverage to acquire a couple calendars. He called the local UP office for information about how to procure the calendars. They asked him where he was located (at work) and minutes later a car arrived with a man carrying a stack of calendars into the company headquarters. He brought one home for me and I still have that 1969 calendar.
This reminds me of a time in the early 1960's when I was talking to my dad about the Milwaukee Road for what I believe was a class project or essay on transportation. He said "Why don't you write the company expressing your interest and need of information", which was done. Very promptly a large manila envelope addressed to Master Brussels Sprouts arrived, which was thick with information including two 8x10 b&w photos, the subjects being a set of boxcabs and a steeple cab switcher. The gesture made this youngster quite an admirer of the company. Still have the envelope with contents.
