This is the last nearly-annual issue Dennison published touting their Halloween party goods line. They tentatively began the practice in 1909, and didn't issue another issue until 1912. From that year through 1935 Dennison issued an annual issue except for the years 1918 and 1932. Their names and formats changed over the years, as did, most importantly, their utility in assisting modern day collectors in piecing together when products were first produced and then for how long. The publication title changed from Bogie Books to Party Magazine to Parties to Hallowe'en Suggestions to The Party Book to Hallowe'en Parties. The issues through 1924 are the most detailed. Those published during or before 1921 are the most coveted, reflected by realized prices.
