Classic records sleeves.

I am looking at the lp from classic record , Stravinsky the firebird Dorati on discogs in europ. The sellers whom I asked said me there was no writing or stickers on the sleeve which said classic record.
On one classic record I own it's written classic record at the bottom of the sleeve on the back.
I fear to get a speaker corner one and pay it the price of a classic record one. Any advices ?
