Betty Barclay what appears unworn ladies shirt with retailer Banana print stated size 34" chest

An American looking label but made in Germany, it's a 'hard to decipher when' with a late 60's- early 70's design. Fascinating for it's manlike attributes and of course that print! Feels like it's new and wow how well constructed is this one. All cotton shirt with superb buttons and checkout the back detail…either side an open seam (hope that's the terminology) retailer and the sleeve has slits.
Stated 34: 17” p-p/ 15.5” waist/ 16” across base hem/ 14.75” shoulder/ 23.5” length
