Hi without reading properly which is probably a habit of mine I presumed you were after a pattern of a parrot. I am on my phone so on enlarging your post and careful reading I discover it’s the sewing pattern for the blouse. Apart from suggesting you search eBay I’m sorry I can’t help.
Yesterday I went through a bag of old patterns from the 1970’s and found a pattern for a huge tiger. I have kept it as a memory of the fun we had with it but the many blouse patterns will be given away. Good luck with your search

Try contacting the pattern companies. Since you have a picture, it could be helpful. Hugs. Nan

Suzanna, what a beautiful shirt, it looks so good on you and you are such a beauty.
I also love the Macaw you are holding, they are such magnificent looking creatures.
Sorry I can't help you as I don't recognise the pattern, but I hope someone does. Love Chris

I sewed a lot back then but do not remember this shirt and I love the look of it. Sandy

That is a big parrot! You look wonderful! I do not remember that pattern. sorry no help here.

Sorry but no help either. It is a lovely shirt pattern and the wearer looks pretty good as well. 😊

Suzanna, I have to agree with everyone here, you are beautiful.
Many of the pattern companies are now offering vintage patterns. Here are some sites to help in you search. I hope that you find your pattern.

Hi Suzanna, do you have a Hospice shop or SPCA shop where you are,
as here in South Africa we have these and they are donated all old patterns. Hugs from Maureen

Suzanna, I have been searching to no avail, for this pattern. I can't tell if if has set in sleeves or raglan, but if you have a loose fitting top with a collar, button up pattern I don't think it would be that hard to make your long, no lapel, boxed front placket. Couldn't you fold back the lapel part of your pattern before you cut your fabric? Fold it to the inner edge where your placket begins and square off? I'm sure jenne has better tips than me, when garment sewing, but I think you could adjust a pattern if you have a loose fitting one.

I will check but do not think i have it. If you do fin d the pattern please share the number bcause it looks very nice, great picture of you!

I don't recall that pattern either, but it is a great shirt! Sometimes I get intense about finding a certain thing and have been know to search for over 10 years for a fabric and it did get reprinted. Don't think I'd do that again, but I understand why you are wanting this exact pattern. Cute photo!
