1925(?) RINGLING BROS CIRCUS POSTER THE REAL DEAL?

Bought this off a friend who found it in a storage unit he won at auction. In the lower right corner says: Strobridge Litho Co. & in the lower left corner: P-8______1925

It measures 34.5" x 23.5" & the paper appears either to be either legitimately old and yellow - or it's been stored too long/exposed to elements too long.

OR(!) - it's the correct pulp/rag paper used for posters that are going to be torn down & tossed in a week?

Is it a winner?

Thanks; I appreciate any help!

Don't see a whole lot of value in yours since it's in rough condition

I'm thinking not original 1925.
