The first photo seems to be a very early photo of the Cunningham Sugar Refinery. It may show the refinery just after it was built in the mid 1890s. The camera is looking northeast from the location marked in the second photo, which was taken roughly 30 years later.
I included notes of annotations on the reverse side of the 2nd print. I know the photo was taken before 1923 because the Three-Bay Warehouse has not been built. Notice the location of the mule barn on the south side of the railroad tracks. We know that location was the first home of the Sugar Land Motor Company. The wooden railroad depot appears in the photo. It was replaced in 1927 by the stucco building which was moved to Commerce Green Blvd. in 1985. The wooden depot sat much further east than its replacement. The 'new' depot was located nearer Ulrich St., which does not appear in the photo.
The last photo shows construction of Pan House No. 1 in 1927.
