   ASL SMM — studiya sahifasi

   Bozorcha bilan BITTA oiladan: bir xil iliq qog'oz fon, bir xil shrift,
   bir xil za'faron urg'u. Ular bitta kompaniyaning ishi ekani ko'rinib
   tursin.

   Farqi — OHANGIDA: studiya sahifasi jim, mahsulot sahifasi jonli.
   Bu yerda tent chiziqlari va rangli taxtachalar yo'q; oddiy chiziqli
   kartalar va bitta urg'u rangi.
