MAEDA-Wada D11 tourist sheet underprints

Maeda's affiliation with the Wada works is well documented ...  his sets appear unused on his editions of K-series tourist sheets.   what is shown above are 1876-1883 kobans.   to date, no K sheet offers this set.  however, I discovered the set as underprints, on Wada D11 tourist sheet.   the D12 sheet also bears the underprints.   though printed on sheet, genuine new kobans and fakes were applied overtop.
