Is this Portacio signature from 1991 real? 0

[Lausy1]

I bought this Uncanny X-Men 282 from Heroes Cards & Comics From London, Ontario in 1991 on the shelf. They had a stack signed copies beside their regular copies with a placard stating “Signed by Artist”. The signature is on page 3. The comics were already signed and I didn’t see the actual signature process.  

This doesn’t look like any signature I’ve seen online from Whilce Portacio but I’ve also not seen any from 1991.

Does anyone recognize this signature?

I also have Uncanny X-Men 275 with a supposed Jim Lee signature on an interior page through the same process at the same comic shop but it looks identical to ones I’ve seen on cards from 1991.
