I have 3 Betty hobos, one in the Chamois color, one in Black, and one in Cobalt Blue...Two were purchased at Diabro.net, so I know they are authentic, and the Cobalt one was purchased on eBay and authenticated here. I love all 3, but I now have a question about the leather. The reason I am writing now, is that yesterday I posted about purchasing a Patent Betty satch with a chain. Most people said the Betty's with the chains were heavy, but one person posted that it was the Betty Totes with the chains that were heavy, not the Satchel that I was interested in. I was then curious if there were 2 different types of leather used for different bags, as my 3 Bettys are all extremely lightweight, (they are the hobos without the chain, like the picture below). I looked at a number of pictures on eBay, and in the archives, and it looks like the leather on the older Bettys was thicker. When I purchased them from Diabro.net, they did have two in Black, one in calf leather, and one in goat leather, with the goat leather one being $400 more, so I opted for the calf leather. Now I am wondering if there really was a choice. Can anyone shed light on this! Thank you!!!
