Beatles Butcher Album 1st state 1966 with shrink wrap

Wondering if this is an authentic Beatles Butcher Album.  It has all of the markings of an original (T2553, RIM with a number 6 outside the circle, Capitol Records & EMI labels).  Because it is still in shrink wrap I cannot see the sleeve color.

From what I have read, it appears to be an original.  The reason I question it, however, is that there are no "air holes" on the album.  Did all originals have the airholes?

Aslo, the measurements are:  12 3/8 inches x 12 3/8 inches. Is this an indication?

There are no seams whatsoever.  It has the verbiage on back at the bottom: "This monophonic microgroove recording is playable on monophonic and stereo phonographs.  it cannot become obsolete.  It will continue to be a source of outstanding sound reproduction, providing the finest monophonic performance from any phonograph.

Under that it says:  Made in U.S.A. Factories: Scranton, PA. - Los Angeles, Calif, - Jacksonville, ILL.

Hope all of that helps.

Thank you so much

Excellent
