Circus - stamp pad on first day sheet, USA

Allegedly - and we really have to say "OBLIGATORY" here - there are no first day covers, but on order and without having to purchase the whole yearbook, a first day sheet with first day special cancellation! We say at this point quite deliberately supposedly, because the information policy of the US Post is here, to put it politely, at first cautiously. Therefore our recommendation: Get a copy of the first day sheet of the toothed circus block from the USA!
