Faahfaahin habka horumarinta taariikhiga ah ee budada cinjirka ee dib loo kala diri karo iyo koolada dhoobada
Horraantii 1930-kii, xirayaasha polymer-ka ayaa loo isticmaalay si loo hagaajiyo waxqabadka hoobiye. Ka dib markii kareemka polymer si guul leh loo geliyay suuqa, Walker wuxuu soo saaray habka qalajinta buufinta, kaas oo xaqiiqsaday bixinta kareemka ee qaabka budada caagga ah, isagoo noqday bilowgii xilligii ...Sii akhri -
Budada cinjirka ee dib loo cusboonaysiin karo waa nooc ka mid ah xabagta budada ah ee lagu sameeyo qalajinta buufin gaar ah.
Budada cinjirka ee dib loo cusboonaysiin karo waa nooc ka mid ah xabagta budada ah ee lagu sameeyo qalajinta buufin gaar ah. Budada noocaan ah ayaa si dhakhso ah loogu kala firdhi karaa kareemka ka dib marka lala xiriiro biyaha, waxayna leedahay sifooyin la mid ah kii hore ee looshanka, taas oo ah, biyuhu waxay samayn karaan filim ka dib uumiga. Filimkan ayaa...Sii akhri -
