Drywall manufacture?

Can someone tell me the manufacture of drywall with the stamping shown on the attached photo?

Thank you,

Not me… but… perhaps this helps…?

Thanks Jeff, that was the first place I looked and couldn’t find it.

If you can, get to the edge and the manufacturers sticker may be there. Where was the picture taken, an attic, wall, etc.?

like Eric said
always try and get an image of the end tape
the very best way to positively id mfr
