PRICE REDUCED!  Very unique vintage unused not dated calendar - 4 1/4 X 5 inch wooden plaque with bird carved/etched/burned and colored on front.  Hanging cover says DAGEN OM AANTE DENKEN, which according to Google translate is Dutch for Days to think about it.  Cover and 12 calendar pages, one for each month, hang by a tied cord from the wooden plaque.  Months of Januari through December, also captioned in Dutch.  The calendar could be used for any year since it does not show the days of the week, only the numbers of the days.  There is penciled neatly on the back of the wooden plaque "For Roy Smart, Junior."  which can be erased.  No other writing, no tears.  Could be one of a kind!  I believe it is the artists initials burned onto the back of the wooden plaque.  So, hanging, the entire calendar measures 10 1/4 inches tall and 4 1/4 inches wide.  Have no idea when it was made - purchased from a local estate sale.  Postage $5.00.
