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.
This product is featured on page 59 of the Spring 1993 Starting Line: Apple Marketing Communications Catalog. Its description reads:
Wear our adhesive-backed, embroidered logo appliqués proudly on your lapel, or add them to the cover of event materials. They’re outstanding giveaways. 250 per roll. APL520
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 20mm x 25mm for stickers on the plastic backing, and 18mm x 23mm off the backing.
