16th/17th Century Woodblock Printed Temple Slip?

I bought the attached (printed on both sides) 16th/17th Century Japanese or Chinese Woodblock Printed Slip/Note from an Antique Shop here in Japan.  Store was unable to translate or tell exactly what it is since it's written in archaic script - but suggests it may be a Temple Slip from comparison to similarly printed temple slips with Buddha/temple gods from the same period.  Can anyone please help shed some light on what it could've and what's worth?
