Never heard of this until now. Interesting.
I remember they came around my house once when I was an adult trying to get new customers. We never did buy but I was interested. Used to see the trucks on occasion. I assume it just wasn’t big in Houston.
We always lived in the burbs or the country, so I’m not the right sample size I guess.
My family bought a lot from them growing up. They sold giant tubs of ice cream. I remember that for sure.
I honestly didn’t know they were still in business though.
