Ladies’ publications such as La Belle Assemblée, Ladies Monthly Museum, Lady’s Magazine, etc. were not merely fashion-oriented. Each issue had one or two fashion prints, a portrait engraving of some celebrated person (usually a woman) and perhaps other illustrations. Ackermann’s Repository, which was for ladies and gentlemen both, also had prints of furniture, homes, inventions, etc. The remainder of the publication consisted of articles.
I am not aware of any publication that consisted only of fashion prints, although people could remove the fashion prints and have them bound up together. I have one of these myself.
Correction: The Journal des Dames et des Modes was a weekly publication and thus there were around 5-6 fashion prints per MONTH.
More commonly, people would collect individual issues and have them bound together. I have quite a few of those, occasionally with an issue or two missing. (Somebody’s dog probably ate it or something.) If these were in a Regency home, however, they would be up to a year old, which is a long time in terms of fashion.
It may seem nit-picky, but I twinge when I read a story where a lady picks up Ackermann’s and pages through the latest fashions. The latest Ackermann’s would have TWO fashion prints.
Just a friendly FYI.
