The Hallmark Cards GC1450 Greeting Card Organizer is a book with 12 compartments for the months of the year. The user can buy and sort greeting cards in advance. Each month's compartment has a calendar for that month and a designated space for birthdays.
The model on Amazon is durable, with a semi-rigid cover, and it can stand up like a book on a shelf. There is space on the front of the monthly pouches for addresses and birthday or anniversary dates. Some versions come with 31 lines on each page for the maximum number of days in a month, but older models are one or two lines shorter. The lines are not numbered.
The Amazon page notes the dimensions of the holder are 8 inches wide by 9.5 inches high by 3/4 of an inch thick. The cover of the model in question has a butterfly, flowers and the inscription "Special People to Remember" on a tan paisley background. It is spiral bound.
The Hallmark Greeting Card Keeper Special Days Organizer is also available on Amazon. It includes similar features but has tabbed dividers for each month, and the spiral binding is covered on the outside. The cover pattern is a bright, abstract floral print. The lines in this model are numbered, unlike the GC1450 model.
