Yes, I am very familiar. I grew up very close to St. Anthony's...and I walked along Yellow Creek from Hamilton Lake, where the Briar Hill Furnace still stands (or did 20 years ago when I lived there). The classic Briar Hill that I remember had a medium-thick crust with quite a bit of sauce, with green, and sometimes red peppers cut in slivers in the sauce...and only had shake-cheese on it, maybe a parmesan/romano mix. Very good. Your pizza looks delicious, by the way.
I remember going over friend's houses and tasting their Grandma's pizza. Many times it was just dough from Schwebel's bakery...sold two per package...for the crust...then press into a rectangle pan. The Grandmas sometimes would cut garlic into slices, and press it directly into the crust...to make a sort of garlic bread crust. Then just a light smear of home made sauce (made from Redpack tomatoes that I can't find where I live now), and light cheese...probably mozz and provolone mix...sometimes a little white cheddar...and sometimes a little sprinkle cheese. This was more of a sicilian style.
Could really go for a slice of sicilian from Bruno Bros. or from Salvatore's right now. Used to like The Elmton Pizza...and Wedgewood in Austintown too.
