I would think I am not alone on this.
Sometimes what may prompt me to buy a piece is knowing the history behind it. I seldom do research but instead relly on my own memories to dictate what will be believable on my layout. There are times when I see something I like but cannot determine if it would work with the rest of the layout.
I suggest the manufacturers consider showing a brief history and era on the outside of the packaging so a less informed individual can decide to purchase or not.
How many of us have seen something really interesting but could not determine the era or proper use. Maybe I am attempting to get out my homework again but this would help me and I know many others to decide. Think about it for a moment before you jump to a conclusion.
If I were a shop owner, I hope to be one day, I would try to have a history available to the public for reference. It would drive people to purchase more.
Just my opinion.
