Had the same idea for Lionel's Design Your Own Boxcar Contest but was insufficiently satisfied with the artwork to submit these. Artwork too rectangular maybe? BTW these are my own photographs and artwork so no risk of copyright infringement.
Update: Conductor Earl's comment below reminded me of another reason this two-sided boxcar commemorating national parks was never submitted to the aforementioned contest. The National Park Service arrowhead logo carries a registered trademark, permission for use of which is limited to purposes contributing to their work. Suppose boxcars could be sold in park gift shops to contribute but offer no assurance that idea would fly. I have replaced the original photographs with the NPS logo removed in the modified photographs but left a shadow where the logo was on the right side of the photographs so one can see the original intent. I apologize for the oversight.
