There exist Voos pattern armys with no trademark. I saw some at the MAX in 2003.
The unmarked Voos patterns are out there but are definitely less desirable. They typically have an orange trolon grip, as opposed to ivory, as well. These unmarked examples routinely run half the cost of a marked example but are still nice enough, especially for someone on a budget.
I got a marked Army a few years ago and have been very happy with it. The unmarked are for sure harder to sell.
