Left voucher broken at edge, lower right corner with dampstain.
Rare in this form, and with numbering and signature on the back.
This is the second of the currently offered 3-piece sections to have a signature on the back, with the signature only on one of the bills. In general, Piotrkow vouchers with a signature are considered very rare, perhaps due to the fact that a sheet was signed (in one place) rather than individual vouchers, so it was only found on one voucher from the sheet.
