Watch List notes:

Simonetta, Bono, and Renzo Riva. LE TESSERE EROTICHE ROMANE (SPINTRIAE), QUANDO ED A CHE SCOPO SONO STATE CONIATE. Lugano, 1981. 8vo, original printed boards. 44 pages, including 7 plates. French, German, and English summaries. Fine. Quite scarce and always popular. A good book to show friends who find numismatics dull.
