Let me share my experiences with ACW magazines, framed prints and books...
Magazines: I began subscribing to CWTI in the early 80's and America's Civil War in the late 80's I stopped both subscriptions in the 90's or early 2000's because I no longer found the articles to be interesting and able to keep my attention. I periodically would buy ACW related magazines if there was an article that seemed interesting but have not bought a magazine in probably 10 years. I ran out of room for the magazines years ago (after shipping them cross-country - fortunately at my then employer's expense). No one was interested in taking them, so they all ended up in the recycle bin.
Framed Prints: I obtained my first print in 1984: Dale Gallon's "Action Front". I believe that it was his first and it may have been the one that started the ACW framed print craze. I have a few more but this is my favorite. I purchased framed prints because, one, I liked the subject matter of each one and, two, I believed the mantra that there might be some future investment value. Now that my wife and I are looking to downsize our housing, I have been trying to sell all of them (except "Action Front"). Offers that I have received have been less than what it would cost to ship them. Thank gawd I do not have to rely on the investment value to eat.
Books: I started collecting ACW books long before the magazines and framed prints and have a sizable ACW library. Downsizing has forced me to make some tough decisions. Used book stores have little interest in purchasing ACW books and public libraries, at least where I live in Colorado, refuse to accept any book donations.
That is my tale, sad but true (at least to me). Curious to see if other folks have the same experiences.
