Very cool. I did not have that link. I had read descriptions of the various stamps, but had never seen a sit like this with pictures. I'm not sure I see much difference in the 50's and 60's stamp. What am I missing with this? Maybe with a different picture I can see it.I would also like to know what this particular set of hats were called, if they were given a special name in the catalog, eg. New Beats, Quick Beats, etc.
Glad that the site is helpful :-)
The difference (which is tricky) between the 50's and the 60's stamp in the site is the 3 dots in the Arabic text. If you take a look, you can see what I mean. In the 60's stamp ( and in yours), there is a triangular shape of 3 dots in the Arabic text.
