Tom MacWood,
I just emailed a photo of the 4th green at Merion from the 1981 Open yearbook to Tommy Naccarato hoping that he will post it for us. I agree with you that the style of the bunker surrounds and depth are different today than they have been in the past and is not sympathetic to the Wilson, Wilson/Flynn, Flynn, Flynn/Valentine, Valentines look. The bunkers today are deeper and nearly all have a much more robust grassy roll down to the sand. The fescue and grasses along the bunker margins today hide the grassy rolls and make the whole presentation far better. Although I do like the previous look better, the direction the bunker surrounds are taking now are in a very positive direction.
You will notice once the photo is loaded that the bunkers presently fronting the green are not in the 1981 photo. According to the Flynn drawings, there were no front bunkers at all in 1924, a single one on the right in 1930, and the complex we see today is shown on the 1934 drawings. At some point, the bunkers were taken out (I'll have to find out when) but returned in the recent remodeling.
Tommy Naccarato,
I tried to call you a few minutes ago. Please check your email and post the 1981 photo. I'd love to see the 1931 photo shown as well.
