ok...I know I'm just dreaming here but how interesting would this be...& Lionel or Mike...if I've hit on something here, feel free to take my dream & run with it :-)
My son and I did a little Christmas shopping yesterday...found a games and puzzle place right in the middle of the mall & picked up this little "Toy Train In A Tin". For the 9 bucks it cost I didn't care whats inside, I just loved the idea...of course I was immediately thinking "tinplate".
Now how cool would it be for Lionel or MTH to take something like the smaller O Gauge clockwork sets that American Flyer used to offer....the ones with the smaller cast iron wind up locomotive & tender, a few pcs of track & a couple cool tinplate cars and pack them all up in a really nice tin box that displays as good as the trains themselves... these little Flyer sets weren't too large at all, the set pictured is in a 12" by 12" box...heck, leave the track out, add some padding and away we go! Put me down for 3 of them :-)
Asking too much?...ok, how about take something else smaller and just as cool, say the little Bing tinplate cranes, put me down for three of those also! (or anything small and cool like that) or a whole series of cool smaller trains...do the same thing, package them in a neat tin box...tinplate in a tin...you get to enjoy the trains, and look at a box so cool you'll never be able to bring yourself to tuck it under the layout....
I'm sure there are a thousand reasons why you couldn't or shouldn't do this but that's the fun part about dreaming...sometimes dreams do come true...and I guarantee that would be a year no one could say "there's nothing new in the tinplate catalog!"
