Thank you for visiting this page. If I'm anything like you, we both have a gazillion dupes of 1987 Topps cards.
In the summer of 2015, I opened four wax pack boxes of these cards as well as a box of rack packs. I've made a Google Docs Spreadsheet of the dupes that I have as of 7 March 2017.
If any are of interest to you, please contact me: peterksteinberg AT hotmail DOT com.
