Original Enamel Advertising Sign "Smilax" Cigarettes 36 x24 inches. ?

Stunningly visual and rare pictorial packet sign. This packet had 12 instead of the normal 10 cigarettes in it. It dates from c1930 and has no chips or damage worth talking about. Please see my other signs on Gumtree. I have had this on my inside wall for over 30 years and it has gone up in price since I bought it-it should continue to do so.
