While doing some inventory and clearance recently, I came across a small notebook/calendar I picked up somewhere, some time ago, to be less than specific. It spans the 1913/1914 year from July to June (I'm not sure why the odd range) and was sponsored by Bromo-Seltzer, an antacid that dates back to 1888.
The first pages were left blank and intended to be used as a notepad. Someone took advantage of that and wrote their Christmas list. The note is old, but I don't think it is comtemporary to the calendar's issuance based on the items requested.
It also lists popular antidotes for poisons. The cure for Opium overdose sounds a lot like the cure for a hangover.
It still stands.
The hours are marked by the letters in Bromo-Seltzer:
Take it easy tonight, and if you do overindulge, remember Bromo-Seltzer.
