Thank you, I'm not an expert, but the Houston Bag looks different on the internet, or am I wrong? .This bag is t from 1970, there is a check and packing, the date of the check is 1972, partially there is some other information, but since the check is almost 40 years old, it is very difficult to consider more information
There is a photo of this particular bag in the Vuitton [bible] "Louis Vuitton City Bags, A Natural History", with the date of 1980. This is where I found this information. LV frequently takes names of older bags and applies them to newer models, which is in this case. The Houston bag you are referring to is the one from about 15-20 years ago, crafted of Vernis leather. Since you have paperwork ("check'' and "packing"??) perhaps a visit to the boutique can shed more light on this piece.
