Hello,
I have been happily writing with my Omas Cotton Resin Bologna for a couple of days now. After I figured out that it wasn't a piston filler and realized that the section was just a tad snug, I opened it and filled the converter with Herbin Poussiere de lune.
My question (and I do have one) is : What on earth is the logo on the top of the barrel. Is it a woman is it a man and a woman or am I hallucinating (yet again) and seeing something that really spells out OMAS.
Please help me.

You're not hallucinating. I believe it is the silhouette of a man and a woman in 20s or 30s get up and style. Here's a color copy from an ink box, I believe.

That's it indeed.They have used that logo for many years.
