simon bisley something on the back

after buying 2 pieces i discovert both of em had something on the back.. since they where both for the same tradingcard job, i thought they might be from the same piece of paper.. and as it turned out.. they where.. this is a prelim that got cutup into 2 pieces.. flipped and reused.. i thought it be nice to share this with you..
If anyone knows what this is or what it was the prelim for ..Do let me know.
I hope you enjoy this one as much as i do..
