In a nutshell: The manual and disks definitely look as though they were released at some point. Many of the clip art images are simply MacDraw versions of the images found in other Apple clip art products (i.e. Art Bits, HyperCard readymades). There are also several files of graph templates (including 3D graphs that look better than what current spreadsheet programs can produce). A few are new to me.
Details: There are two 800K floppies. Both are blue (like most 1989-1994 Claris floppies) and have white wraparound labels (like most pre-1991 Claris disks). On the front of both is a black and white photograph of a pair of scissors cutting a piece of paper. The words "ArtFiles Clip Art" are written at the base of the label, with the disk number (1 or 2) in a circle next to the writing. The Claris logo is in the upper left-hand corner (as it is on all Claris floppies). The part number on the disks is U90-365-013A. The font used for the "ArtFiles..." writing is the same font Claris used on all other products of this vintage. The copyright date is 1990.
A 17 page manual accompanies these disks. The manual is paperback, not overly large, and has drawings of a newsletter, slide, t-shirt, and mug on the front. All have a "Flight for Sight" logo on them. The manual is officially titled "Claris ArtFiles Clip Art Reference Guide", with a subtitle that reads "Includes printed examples of MacDraw II templates". On the inside cover are directions on how to access the images. The first page is a table of contents (contents are listed by disk number). Pages two and three give examples of where and how the images can be used. Pages four through sixteen show the images.
Page seventeen is what makes me believe this could have been some tie-in with MacDraw II. This talks about additional templates, namely borders, that can be found in the "Dictionaries & Templates" folder that comes with MacDraw II (on the main disks).
This is the fourth copy of MacDraw II I have opened (I have a fifth but am keeping it shrinkwrapped; it's identical to another one I own) and is the only one that this set of floppies has been inside. The other MacDraw IIs I have appear to be from late 1988-early 1989, late 1989, and late 1991-early 1992. I'm placing the date of this one sometime in late 1990-early 1991.
If anyone else out there has boxed MacDraw IIs, let me know if you got any tie-ins with your copies.
