Almost nothing is known about this project except for the name, that it was American in origin, it featured a giant monster of some sort and that it was considered possibly around the late 1950s to early 60s. Although we here at UGMM try not to post subjects of such limited information, we're stuck with what we have here and hopefully one of our visitors will shed more light on GIGANTURO.

Special thanks to Eric Hurd who brought this project to our attention, though even he's in the dark about it
