This is arguably among the very best invitations Dennison produced. I appreciate the many elements comprising what is a tranquil scene. I also like the bold blue used for the cauldron smoke. This invitation first appeared in the 1924 Bogie Book, stock number H87. If you collect unused Halloween ephemera, this is a great one to make part of your collection!
