Is This Vertically Laid Paper?

Just curious if this is vertically laid paper?

No, you are seeing the pattern of the applied gum.
Please show an image of the front so we have some context.

Sorry John
It's a SG#907
It was face down when I seen it so it threw me off
Never seen it before
But know it know thanks!

I agree with John - the pattern of 12-13 'stripes' from top to bottom of the stamp is from how the gum was applied. You may also notice, in the other direction, 4 or 5 'waves' from side to side. Those are a remnant of the Rotary Press. Laid paper is from the paper manufacturing process - this is not on laid paper. There are all kinds of things that can easily be confused with being all kinds of other things.

The frequency of the gum ridges are one of the identifying features of various printings of the 1922 series. Very helpful in weeding out forged Kans, Nebr overprints.

The small vertical lines are from the web fed Stickney rotary wet printing press gumming station gum rollers.
A large horizontal line or large horizontal lines are from Stickney wheel and bar perforator gum breaker bars.

Thanks for letting me know!
It was my first time seeing this
everything mentioned makes complete sense
I'm glad there are sites like this

Perhaps a moderator could move this thread to the appropriate US Stamps forum.
