For as long I have purchased Apple products, and even before the original Macintosh in 1984, Apple has included stickers in its devices featuring the Apple logo. I have examples in my collection of Apple logo stickers from before the Macintosh in the early-1980s.
I added these stickers in late 2020 when the new M1 Macs were released. These stickers were included with the M1 MacBook Air laptop in Space Gray.
