Vintage Lacoste label information, to trademark, no izod?

Hi all, I believe I have some very late 1970s Lacoste polo shirts from the mid/late 70s but nothing identifying in the label resource here. Though it might be one to add if we can get the right dating. It has the Norma Legge 1973 on the fabric label so must post date that, also Lacoste registered their trademark (sans Izod) in 1979. So I think we have a good dating of between 1973-1979.

However aparently Izod and Lacoste did not part ways till much later.

I am thinking that this label must have been when Lacoste started to use the label without Izod mention and before they registered their own specific trademark without Izod. I have found 70s adverts with both names being mentioned and also with just Lacoste.

If we could date it accurately maybe we could use it for the label resource? Pictures attached.

 

Thanks so much for that

My only reason was because it was the one I found that dated after 1973 (which I looked for because of norma legge 73 info on the fabric label). It appeared that the registration is due to end in 2030? I am not very familiar with researching trademarks so any advice on this would be very helpful.

 

Yes exactly no trademark at all. The only thing that I could think of was some kind of trademark issue when they parted with Izod, but seems unlikely now. I’m not sure if they had occasions to produce the line without the trademark? There’s certainly no issues regarding authenticity. Do you think the shape, style, slim fit, indicate 70s?
