Actually, now that I think of it, I'm not sure this could have been an old Lucky - there was a Lucky down the street at Stockton and McMahon (5924 Stockton), later Albertsons, and now a DD's discounts. But that could be a replacement store for this one, if this was Lucky.
I did get more photos of this place on January 28th (all now up in my site's Sacramento section).
Here's an alternate view of the pylon:
That section of south Sacramento, the Lemon Hill/Elder Creek area, has quite a bit of older retail buildings - a gabled supermarket at 6418 Stockton was originally the local Food City chain (not to be confused with the national chain), was later Mike's (an independent with still one location up in Carmichael), then Khanhingtong Supermarket, and after a change of ownership this past November, New Asia Supermarket.
Right next to this supermarket, at 6035 Stockton, is a former Kinney Shoes building, now a restaurant and the Khanhingtong Oriental herbs retail unit (they used to operate both this and the old Food City).
And as mentioned earlier in the post, there's old 1970s Lucky at McMahon and Stockton. I actually went there twice before it closed, when it was Albertsons.
I did some research in the Sacramento Bee archives and found out that Wing Wa began operating at 6021 Stockton in 1987 or so; in 1989, the owners were hit with a $70K fine for accepting food stamps for non-food items (the largest in the county ever at that time). Obviously they've managed to get past those hurdles and continue operating - and Wing Wa has been nicely featured in several Bee articles since then.
That ceiling does look a bit more vintage than two decades old...
