These multicolor Apple logos are made from embroidery thread and have an adhesive back. One set of embroidery stickers are on a transparent plastic film with the adhesive still tacky, and another set are separate with dried adhesive on the back. The adhesive on the separated stickers is yellowing.
Because the stickers are made primarily of thread, each has a slightly different shape, especially the individual stickers with hardened adhesive backs. The individual sticker dimensions vary, but the least-distorted example measures 20 x 25 mm for stickers on the plastic backing, and 18 x 23 mm off the backing.
I have estimated the date of these stickers as 1988 because a friend of mine had one of these on his hat throughout the mid- to late-1980s. I believe my friend acquired his sticker at an education event in Chicago. My set of stickers was purchased from the estate of a former Apple Education employee.
One year while visiting a Chicago-area Apple Store coincidentally on Halloween, I noticed that Apple Store employees were giving away Apple-logo items to Trick-or-Treaters. I waited until after designated Trick-or-Treat hours were over, spoke to an employee, let him know I was a collector, and asked for one of the “treats.” The first year I discovered this Apple-logo item giveaway, they were giving plastic Apple-logo flashlights. I have since visited Apple Stores on a few other Halloweens and, for at least two years in a row, they were giving these LIVESTRONG-style wristbands.
These Apple wristbands were from approximately 2015, and I got them at the Northbrook Court Apple Store. They are child-size rubber bracelets in either orange or white with an embossed Apple logo. They measure approximately 60 mm in diameter and are 12 mm wide.
This thin plastic mousepad made from materials by the company Microthin features the blueberry Apple logo printed in a manner to simulate the translucent plastic Apple used in the iMac line of computers at the time. This mousepad is blue to match the blueberry iMac. Other versions of this design were available in the other five iMac colors: tangerine, lime, strawberry, grape, and graphite.
The bottom of the mousepad is covered in printed dots that provide traction to prevent slippage. The stickiness (tackiness) of the material is still viable after about 20 years and can be reactivated by rinsing any accumulated dust with water. However, the entire mousepad is beginning to show signs of yellowing.
