Being Artistic... Genetic or Honed Skill?

My two oldest sons have been showing interest in arts. Painting, drawing and coloring to be specific. I have compiled maybe at least a thousand pages that are keepers. I am not sure how to archive them yet. For now I am placing them inside a clear plastic and inserting them into a ring binder.

My wife and I are always having fun whenever the issue of where our kids got their artistic skills. I would always refute her when she says "they got it from me!". I always say that it must be from me as I have an art collection too. I have it stashed somewhere (If I can only remember where). If it was performing arts, then maybe it was from he. Hahaha!

They recently submitted one of their work at my wife's company that held a drawing contest with a theme "Safety". They selected 13 entries that they used in their 2011 calendar. Aloysius and Achilles submitted their drawings and they were fortunate to have their work included in the calendar. They also got $50 each as prize. Great job boys!
