This is a series to collect the cover page illustrations by artist Morichan for the semi-annual Azumanga Daioh doujinshi compilation No Osaka No Life he organizes with other artists. These covers always feature the titular character Kasuga Ayumu (Osaka). The series was started in 2011 at Comiket 80 and is still being produced.

Let's attempt to keep this sorted in chronological order.
