Where can I buy pink Peruvian bananas?

I know there are lots of Peruvian markets in Queens, but does anyone know of any places that specifically sell these pink bananas? (here's an example)

My Peruvian grandmother is always talking about these bananas that she used to eat when she was a child in Lima and how much she misses them. She's struggling with dementia now and I would love to find some of these to surprise her with when I see her next week. This woman absolutely loves bananas so I know these in particular would really cheer her up if I can find them.

I don't even know if these are sold in the US. I know it's a long shot, but does anyone know if they can be found in the city? I don't live near Queens so it would be a full-day thing, which is why I'm trying to confirm before I head there. I would even be willing to venture out to Paterson if there is a place that would have them!

Thanks
