Approx 11 x 7 inches-----1920's ?.

 That's a great Diecut

Looks 20's to me 

Relics

It'd be superb, if it was original.  Unfortunately, unless you got it directly from the ITC archives, it's a fake.  This identical image was published in Pipe Dreams.

Thanks Camwal-----No, I did not get it from the I.T.C archives---From the front it's quite compelling,  the creases are real, and the pin holes look old, but there's no back stand to the rear, just all over stained.

Thanks for the advice---saved me a few quid.
