I noticed the mention several times of coffee cards in this issue and in the past. I saw that Arbuckle's offered History, Animal and Sports cards. See ad below for Arbuckles and on top "No. 78 AN ALBUM OF NATURAL HISTORY".
Apparently you could collect the signatures from Arbuckles Coffee and send in for any number of prizes, one of which was these cards.
