WWII Italian Propaganda

Hi i have here a couple of italian propaganda postcard with wrights  "Strike the Enemy Everywhere" I cannot seem to find out anything about them as i have 14 all up I was looking for what the value would be

Here is a link to a site where a lot of this type of material is sold by/for collectors.  I don't see the cards you have pictured here but take a look:  http://cartoline.delcampe.it/list.php?submitted=Y&language=I&cat=857&var=Cartoline-Postali-Tematica-Militari-Guerra-1939-45&action=current&startedtodaynorenewval_dd=1&endingtodayval_hh=24&sort=price_present_ASC&listtype=onlygallery_Y&listitemsperpage=100&nbpage=20&x=10&y=12&page=19&rs_count=1972

I look at a lot of postcards; I would not be surprised to see the cards you have pictured in the $15-30 USD range (they look to have corner/edge wear in these scans.)  An especially striking image (some Italian anti-US propaganda portrays Black US soldiers desecrating churches and/or Italian women) could fetch much more ($100-200.)  Also, I can't read the artist's signature in the lower right; don't know of any Italian artists that command higher prices, but there may be some. (Some German artist have quite a following)
