I'm getting an error in my Index.cshtml file "Cannot convert method group 'DisplayText' to non-delegate 'dynamic'."

Index.cshtml

@model ComicBookGallery.Models.ComicBook

@{
    ViewBag.Title = Model.DisplayText;
}

<h2>@Model.DisplayText</h2>

<div class="row">
    @foreach (var comicBook in Model)
    {
        <div class="col-md-3">
            <h4>@comicBook.DisplayText</h4>
            <img src="/Images/@comicBook.CoverImageFileName"
                 alt="The Amazing Spider-Man #700"
                 class="img-responsive" />
        </div>
    }
</div>

ComicBook.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace ComicBookGallery.Models
{
    public class ComicBook
    {
        public int Id { get; set; }
        public string SeriesTitle { get; set; }
        public int IssueNumber { get; set; }
        public string DescriptionHtml { get; set; }
        public Artist[] Artists { get; set; }
        public bool Favorite { get; set; }

        public string DisplayText
        {
            get
            {
                return SeriesTitle + " #" + IssueNumber;
            }
        }

        //series-title-issuenumber.jpg
        public string CoverImageFileName
        {
            get
            {
                return SeriesTitle.Replace(" ", "-")
                    .ToLower() + "-" + IssueNumber + ".jpg";
            }
        }
    }
}

It looks like this page is set up to expect a single comicBook object as the model:

@model ComicBookGallery.Models.ComicBook
<h2>@Model.DisplayText</h2>

But then later, the code is using the model as an iterable:

    @foreach (var comicBook in Model)
            <h4>@comicBook.DisplayText</h4>

So what does the controller actually give it, a single object or an iterable collection? One or the other of these needs to be adjusted.
