thanks, that's about what i was thinking. not plain enough to be pre-contact, but not new or more recent 'vintage'. would be nice if it were at least eligible for a birthday card from the queen*. ie. 'antique'. i gather 1850 & earlier are the most desireable (and expensive).
as far as i know,
'antique' = over 100 yrs. old, ie. pre-1915, pre-ww1.
'vintage' = a woolly 50 yrs old-ish, with a date or range, ie. early 20th c. or summer 1916.
*- for y'all back home HM Queen Elizabeth II sends a birthday card to all her subjects on their 100th birthday. i wonder if she'll send herself one in 11 yrs...
being a bit younger, than her, i do not think she'll be sending me one. especially as i am not a UK citizen.
