I used attend this show for many years, you describe exactly why this is such a great show, besides being predominantly a gathering of many vintage sellers. Show founder Terry Mawhorter is entirely to blame for such a success. I met Terry in the early '90s at a local flea market in IL. He had a nice collection of vintage, it was hard for me to make up mind over two sets so...I bought them both. He told me about the Ohio Pen Show and I attended every year since up to when I retired about 10 years ago.
Have fun, buy, sell and party like there is no tomorrow!
