Here is an 1851 book bound by Altemus and Co.

Christmas Blossoms by Uncle Thomas. Published by E. H. Butler & Co. 1851

Although this book cover does not indicate Altemus as the binder as the other Christmas Blossoms’ books, there is little doubt that Altemus did the binding of this book. Note the vases on the 1848 and 1849 books. All the vases on all three vases are identical. These vases plus the fact that Altemus did the other two Christmas Blossoms’s books make it a certainty that Altemus bound this book.
