Last time the portfolio was here, there was one picture mounted in a very shbstantial mount. in fact it was so strong and heavy that it had damaged several other prints in the package due to the inadvertent shocks and bumps in shipping.

While that picture was unscathed, I cannot consider it a valuable contribution to the portfolio.

I don't mount my prints for the portfolio - if I did, I would wet-mount them to 2.5mm aluminium.
