Let's take a look at some of the main monthly periodicals for girls.
Shojo (Young Girl)
The above issue of Shojo included a Christmas letter set (as far back as the 1950s, Christmas-related gifts were heavily promoted in Japanese kids' magazines). The second gift was a 53 card set of bromide playing cards. Not bad!
Shojo Club (Young Girls' Club)
|November 1961. Now that's what I call wearing your fall colors!|
|5 big presents in this issue|
|September 1965. I don't believe this is a big furoku publication besides some bromides, but I just had to post this photo. Does anyone else look at this and think Ralph Macchio and Tamlyn Torito in KK 2?|
|November 1977. From the 50s to the 70s (and beyond), the furoku tradition carried on over the years.|
|6 furoku - iron print, bag, high class pencil case, etc.|
However, in girls mags, the furoku were typically stand alone stories. Not only that, but the stories contained in the magazine were also stand alone.
I'm not sure what conclusions can be drawn from these differences, or why they exist at all, but it's a question worth considering.
