Talbot Photography (processor). This is a publicity photo from 1945 used on the cast credit board at the Biltmore Theatre on Broadway. No author was listed. Often publicity photos of that time did not post an author credit as they were taken by theatre companies and studios for publicity purposes. Talbot Photography was the only marker which I Googled and seems to have been a photo processor of that era.
This publicity photo was not copyrighted. Its source is from the Biltmore Theatre on Broadway. It's credited to "Talbot Photography" taken in 1945 for "Snafu" a Broadway play at the Biltmore Theatre in which McVeagh starred. I cropped this photo to cut the size down for uploading to Wikipedia.
