I've actually had this Beatles coloring book for a few years, but the pages are so detailed that I've only done a few...plus I've got other adult coloring books that I do sometimes.
These are the only pages I've done. Here's Can't Buy Me Love:
A Hard Day's Night:
Eight Days a Week
Drive My Car:
Yesterday:
Strawberry Fields Forever:
And I did this page yesterday, Good Day Sunshine:
These always take multiple days to finish, Good Day Sunshine took two simply because I was dedicated and finished some work early.
